A presentation give in the finals of Schenider Electric Go Green in the City Challenge -2012
Fossil fuel consumption in the recent years has been increasing and the burning of fossil fuel is said to be a major contributor towards global warming, acid rains, air, water and soil pollution, forest devastation and radioactive substances emissions. Besides the environment, the fossil fuel prices fluctuate considerably, usually going up and being very expensive in many countries.
Most importantly, the quantity of fossil fuels, like petroleum,natural gas, and coal can only decrease since they are non-renewable resources.
As a result many countries have been investing billions of dollars in new technologies and demand for sophisticated power supply options is greatly increased.
In a typical developed country as much as 40% of total fuel consumption is used for industrial and domestic space heating and process heating. Of this around one third is wasted.
Currently recovering low temperature heat which includes Industrial waste heat, geothermal energy, solar heat, biomass and so on could be a very critical and sustainable way to solve energy crisis. Utilising waste heats along with attempts for the use of renewable sources as low grade thermal heat has motivated us to develop a project based on ORC.

Absorption chiller cycle (NH3-H2O) Driven by Solar EnergyIJMERJOURNAL
ABSTRACT : This manuscript proposes to study by the use of computer simulations and experimental tests, the possibility of applying a chilled absorption (ammonia/water) using solar heat to cooling. Absorption cooling (ammonia/water mixture) is eco-friendly and in addition, can be powered by low-temperature resources. This unit can recover low heat source, with a low temperature difference between heat source and sink. They have good availability, simple start up procedures, good part load and require little maintenance. Computational modeling and simulation have become an important part in studying technologies and evaluating their range of applications. They can save time and money, offer flexibility, enables repeatability, improve control and allow the user to push system and change or add the inputs for get new results., this was the ideal method to devise and test the proposed models and investigate their performance in different conditions. The operation of the absorption chiller cycle, a temperature source of 103ºC and a cold sink temperature of 25ºC for heat rejected was used. Thise energy source can be used to operate ammonia/water mixture chillers, to produce cooling at acceptable thermodynamic ranges and within standard limits for domestic use. The hot water from the accumulator water cycle will supply to the generator of the ammonia/water mixture sorption cycle. The results from the simulation have revealed that the low-temperature solar sources at Al-Joufra city were successfully utilise to generate power. The highest cooling capacity of the chilled water that could be supplied to the community was at a temperature of -15.6°C. In the evaporator of the ammonia/water mixture cycle, the inlet water was 12ºC and the outlet water which will cool down the house by 6ºC (cooling water cycle). These results have been achieved when the cycles were simulated at an ambient air temperature of 23ºC, heat input was 61.8 kW
A OVERVIEW OF THE RANKIN CYCLE-BASED HEAT EXCHANGER USED IN INTERNAL COMBUSTI...IAEME Publication
The majority of the heat produced by automobiles, primarily by diesel engines, is squandered in various ways. If this waste heat is collected, it can be applied in a variety of other ways. Recently, increased emphasis has been placed on the global issue of rapid economic growth, a relative energy scarcity, internal combustion engine exhaust waste heat, and environmental degradation. The remaining heat is released into the environment through exhaust gases and engine cooling systems, leading to an increase in entropy and significant environmental pollution, so it is necessary to convert waste heat into useful work. Of the total heat supplied to the engine in the form of fuel, approximately 30 to 40% is converted into useful mechanical work. At 4000 RPM, the exhaust gas temperature is at its highest. So a recovery system is created for a constant RPM of 4000. A shell and tube heat exchanger and a uniflow steam engine connected to the main engine make up the recovery system. By reducing the frictional power at the main engine's power stroke and idle stroke, the linked steam engine increases the efficiency of the main engine. Due to the additional recovery system, the system's initial cost is significant. But over time, the system turns out to be profitable.
Design &Analysis of Waste Heat Recovery System for Domestic RefrigeratorIJMER

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
