Irreversibilty
The document discusses irreversibility, the Gouy-Stodola theorem, and its applications to calculating second law efficiency. It states that the Gouy-Stodola theorem establishes that the rate of exergy (available energy) loss in a process is proportional to the rate of entropy generation. It then provides examples of applying the Gouy-Stodola equation to heat transfer through a finite temperature difference, fluid flow with friction, and mixing of two fluids. Finally, it defines second law efficiency as a measure of a device's performance relative to its maximum possible reversible performance.
Waste heat recovery from hot gasses in cement industry
This final year project focuses on direct heat recovery in which heat from various units such as the Kiln, Calciner and Clinker Cooler is recovered. For this study, a process model is developed using Aspen HYSYS simulation software, and the model is confirmed against acquired data from the industry followed by calculation of equal fuel saved. The heat recovered from all these units is used to produce superheated steam to run a steam turbine generator which in turn provides electricity to the cement plant. This is an implementation of the Steam Rankine Cycle. This project not only benefits the industry in terms of cost-saving on fuel but also reduces the quantity of toxic hot waste gases. The number of carbon emissions would have increased drastically if coal would have been used instead. The steam turbine was able to generate 14 MW. If this is successfully implemented in all other major industries, a significant amount of non-renewable reserves can be saved for future generations.

The document presents a combined power and cooling cycle using aqua-ammonia vapor absorption refrigeration. It compares typical refrigeration cycles to the proposed Goswami and Srinivas cycles that allow for combined power and cooling output. The proposed cycle uses aqua-ammonia as the working fluid and includes formulations to calculate the net work, efficiency, power output, and cooling output of the cycle. Simulation results show the cycle can produce additional power while doubling efficiency compared to typical cycles. The cycle offers flexibility to produce only power or combined power and cooling, and is suitable for various atmospheric conditions.

This document describes a study on a double solar vapor absorption refrigeration system coupled using a condenser. The study conducted energy and exergy analyses of the system. Key findings include that increasing the collector temperature increases both the condenser load and secondary cooling capacity. The primary and secondary COPs of the system decrease with increasing collector temperature. Higher collector temperatures also increase the reduction in the required collector area for the secondary cooling cycle. The study analyzed the impact of different thermic fluids on the required collector area. Advantages of the system include utilizing the condenser heat load, using variable refrigerant-absorbent pairs in both cycles, and reducing the total required collector area. The analyses demonstrated increased COP of the system and reductions in both

Fouling in heat exchanger network (HEN) in a refinery has been identified as a major obstacle for efficient energy recovery. Fouling causes loss in efficiency over the time, additional pumping cost and loss of production due to additional downtime. A complex crude preheat train (CPT) in a petroleum refinery was chosen in this study to represent an industrial HEN experiencing severe fouling and huge economic losses due to fouling issues. The objective of this study was to develop a realistic cleaning schedule optimization problem. An improved optimization problem for the cleaning schedule of the heat exchangers in the CPT was developed which takes into account the hydraulic impact of fouling through the additional pressure drops. The problem fall into the MINLP class, that is very complex and finding the global optimum is a challenging task. Hence, the recent stochastic methods are proposed and used to solve the MINLP problem without introducing any approximations or simplifying assumptions. Optimizations were performed over an operating period of 44 months following crude slate variations and operating conditions of the refinery. The solution provided by recent stochastic algorithms are global optimum solution. The results show that ignoring the additional pumping cost in the objective function resulted in an optimal cleaning schedule that provides a less savings (18.09% of maximum potential savings) in the net loss compared to the optimal cleaning schedule that utilizing the additional pumping cost in the objective function, which increase about 19.34% of maximum potential savings.
Convergent Wind Mill with Velocity and Acceleration Control
This document describes the design of a convergent wind mill that uses convergent nozzles to control air velocity and generate electricity. The wind mill aims to more efficiently utilize wind power and reduce costs compared to existing methods. It consists of horizontally rotating blades connected to a generator. Convergent nozzles placed in four directions control incoming air velocity before it reaches the blades. Experimental testing showed the design was able to generate voltages from 0.04 to 0.12 volts over the course of a day. The convergent wind mill aims to help reduce electricity shortage and reliance on fossil fuels.

Abstract Poultry production is a lucrative business in Nigeria but inadequate hatchery machines limit the expansion and make poultry products for instance day old chicks more expensive. At the moment, few commercially owned poultry hatcheries in Nigeria are located distance far away in the western and Eastern parts of the country. Majority of these hatcheries have little or no access to the national grid system but operate at about 60 per cent below the installation capacity. Generally, environmental pollution, unreliability and lack of access to grid power supply and low performance efficiency characterize the condition of the poultry hatchery business powered by conventional energy supply in Nigeria. These hamper and adversely affect the establishment of medium to large scale poultry production outfits in the rural areas of the country. But with the advent of electric powered egg incubator technology in poultry production, poultry farmers in Nigeria are likely to incubate and hatch poultry eggs and breed day-old chicks under a sustained power supply in a clean environment. Therefore, this study was aimed at the design, developed and tested in order to provide a favourable environment for eggs hatching. The developed machine was tested to assess its performance. The results from the test showed that out of the total 25 eggs, 5 eggs hatched after operating the machine. This gives 33% hatchability. The results showed that with further improvements, the developed machine can adequately be adopted at the household level instead of rearing chickens for the sole purpose of incubating eggs. Keywords: Automatic, egg turning incubator, favourable environment, hatchability
Production and Performance Evaluation of Pedal Operated Pressed Briquettes
--------------------------------------------------------ABSTRACT----------------------------------------------------------- This paper treats the production and performance tests of pedal operated pressed briquettes of about 220 mm x 80 mm x 67 mm using agricultural and wood wastes. The densification was achieved by using some mechanical pressure to reduce the volume of vegetable matter and its conversion to a solid form within a pedal operated briquette press designed and constructed for that purpose. The characteristics values of the briquettes such as the effects of the binder proportion in the briquette and its effects on the combustion properties were investigated using ASTME methods. The calorific value of the briquettes ranged between 11.50 MJkg-1 and 14.02 MJkg-1, making them suitable for use as supplementary fuel in small scale industries such as bakeries. It was observed that the percentage composition of the binder greatly affects the friability index of the briquette. The resistance to humidity also played an important role in the briquette combustion abilities. This briquetting technique of agro-residues is one sure way of fighting climate change and provides a sustainable energy source due to the fact that it reduces dependence on fossil fuels and converts waste materials to wealth.

This document presents a computational fluid dynamics (CFD) simulation of a domestic direct type multi-shelf solar dryer. The study aims to validate the design of this dryer and demonstrate its temperature distribution and radiation heat flux. The simulation is performed using ANSYS-Fluent software. The results show that the air temperature inside the dryer cabinet increases significantly to around 326K due to natural air circulation. Radiation heat flux contours indicate that the dryer shelves receive sufficient flux to validate the dryer's design for food drying applications.

Numerical Simulation of Solar Greenhouse Dryer Using Computational Fluid Dyna...
Moisture removal from crops and other food items is
one of the ways to preserve them for longer duration. Previously,
drying openly in sun was used to reduce moisture content. But it
had some disadvantages like contamination due to dirt and other
unwanted elements as well as attack by rodents and birds.
Drying in covered close space with vents would be helpful in
overcoming these problems. Solar greenhouse dryers are the
close conduits in which crops can be dried without negatively
affecting the nutrition value. The factors affecting the crop
drying are solar radiation, climatic conditions, material of which
the dryer is made of and shape of the dryer. A lot of
experimental investigations have been done to improve the
drying rate. With the advances in computational power and
numerical techniques, Computational Fluid Dynamics (CFD) has
emerged as a powerful tool to optimize any design. In the present
study, simulations have been done on greenhouse dryer with
modifications to identify the temperature distribution with
variation in wind velocity. Different radiation levels have also
been found out at different locations in the dryer. The model of
the dryer has been created in CREO 5.0 and analysis has been
performed using ANSYS 14.0. The simulation has been done for
both forced and natural convection. Obtained results have been
validated with the experimental work done by previous works.
Better drying rate has been obtained for forced circulation as
compared to natural convection which is in agreement with the
available experimental results.

The behavior of a novel low-profile concentrating solar thermal collector was investigated for an industrial metal processing application requiring 180°C heat. Simulations found the collector could provide 53% of the daily 260 kWh thermal load in Sydney with a 200m2 collector area. With 50% government subsidies, the system had an 11-year payback period and net present value of $69,641 over 20 years due to increased gas prices. Further research could reduce costs and improve efficiency for more attractive economics.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
