Design and simulation of a multiple effect evaporator using vapor bleedingAhmed AL-Dallal
This document describes the development of a model for a five-effect evaporator system used for concentrating sugar solution. The objective is to model vapor bleeding, an energy reduction scheme, to reduce steam consumption. Mass and energy balance equations are developed and solved using the Newton-Raphson method in MATLAB. First, the model is solved without bleeding to obtain the steam requirement. It is then solved with bleeding incorporated, requiring additional heat exchangers. Vapor bleeding provides a 26% reduction in steam usage but requires $150,291 for five extra heat exchangers. Annual steam cost savings of $43,200 provide a payback period of 2 years 5 months.

3) Properties, uses, and hazards of ammonia are described, including its industrial production via the Haber process at high temperatures and pressures using an iron catalyst.
Josh is analyzing a liquid cooling system for his overclocked CPU that produces 150 watts of heat. The stock heat sink can only dissipate 113 watts and would overheat the CPU above 75C within 250 seconds. Several simulations are run to determine the maximum power dissipation of the stock heat sink and a custom liquid cooling system. The liquid cooling system is found to dissipate 147 watts of heat, preventing the CPU temperature from exceeding 75C, while the stock heat sink would overheat the CPU.
The students constructed a single pipe heat exchanger by burying a steel pipe in an active compost pile to study if compost heat could effectively heat water. Water was run through the pipe at two flow rates while temperature data was collected. The experiment resulted in water temperature increases of 1.4°C and 1.3°C for the different flow rates. Modeling in STELLA predicted the temperature increases could have been higher at around 9°C and 5°C if steady state conditions were reached. Faster flow rates led to higher heat transfer rates but slower rates allowed for greater temperature change according to the models.

Low charge ammonia vapour compression refrigeration system for residential ai...RAJESHKUMAR4616
Ammonia is widely used as a refrigerant in industrial systems for food refrigeration, distribution warehousing and process cooling. It has more recently been proposed for use in applications such as water chilling for air-conditioning systems but has not yet received widespread acceptance for this application. This project was envisaged to develop an ammonia vapour compression refrigeration system of 3 TR capacity for residential air conditioning and to analyze the minimum possible charge in order to reduce leakage hazards associated with the system. This would increase the use of ammonia in a more efficient way. It has Zero ODP and GWP which makes it to be environment friendly. Even though Ammonia is a cost effective and energy efficient alternative to conventional refrigerants like HCFCs and HFCs, etc., it is toxic. So, toxicity of ammonia needs to be addressed. This calls for low inventory of refrigerant in individual system. The present work aims at reducing the specific charge of ammonia for residential air conditioning system with air cooled condenser.

Power consumption was also reduced by 17.25% with pure SUNISO 3GS oil and 25.83% with the nano-lubricant oil. The nano-lubricant improved heat transfer and reduced friction inside the
The document describes an experiment to model a pipe heat exchanger that cools water as it passes through a tub of ice. The student measured the inlet and outlet temperatures of water running through a garden hose submerged in an ice bath. The outlet temperature reached a steady state of 17 degrees Celsius within 4 seconds. Modeling with finite differences predicted a steady state of 10.5 degrees Celsius, showing a difference from the experimental results. Decreasing the mass flow rate through the pipe could achieve lower outlet temperatures by allowing more time for heat transfer. Suggestions for improving the experiment included not pre-cooling the hose and using software to better model heat transfer.

The objective was to compare cooling of peaches via free and forced convection. Peaches were submerged in ice baths with one stirred (forced convection) and one stagnant (free convection). Temperature was measured every minute until reaching 7.5°C. Forced convection cooled the peach faster, in 25.14 minutes with a convection coefficient of 3,105 W/(m2K), while free convection took 43.17 minutes with a coefficient of 41.38 W/(m2K). COMSOL models showed faster cooling under forced convection. Differences from theory were likely due to approximations in the experimental setup and peach properties.

The document discusses numerical approaches to improve the traditional process of making jaggery. The traditional process involves extracting sugarcane juice, boiling it in pans over an open hearth furnace, and packing the semi-solid juice. Computational fluid dynamics (CFD) analysis was used to model different pan geometries and evaluate heat transfer rates. The results show that modifying the pan design with fins or additional surfaces improves heat transfer over the traditional pan, allowing for more efficient fuel usage and increased energy efficiency of the overall jaggery making process. Further experimental validation of the optimized pan design is still needed.
Case study Energy Audit for Chiller PlantHina Gupta
The document discusses energy audits conducted on HVAC equipment at a client site by MGCS-Energy Audit Company. It analyzes the performance of two chillers and two cooling towers. For the chillers, it is found that Chiller 2 has a higher condenser approach and lift, indicating its condenser is fouled. Cleaning the condenser is recommended to improve Chiller 2's efficiency. For the cooling towers, Tower 2 has a higher approach and lower effectiveness, suggesting relocating the towers to the terrace for better air flow. The audits identify opportunities for energy savings through equipment maintenance and modifications.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
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.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
