The thermoelectric application is one of most popular energy harvesting application from waste heat. The thermoelectric generators, thermoelectric coolers, and thermoelectric modular devices criterion comes in both sustainable energy as well as renewability of electrical energy from waste heat sinks. The recovery operations are optimized with the help of modeling using MATLAB software. The material science based thermoelectric applications can be modeled with the help of MATLAB simulink modeling. The numerical and algorithmic method of MATLAB modeling is for the development of hybrid thermoelectric coolers and generators (solar thermoelectric generators, radiative cooler, heat sinks). Later, the use of MATLAB software gives opportunities to develop the cost effective and high power thermoelectric generators. The emerging commercial device making is also discussed for thermoelectric generator using MATLAB optimization.

To reduce fossil fuel consumption and its polluted environmental impact, a new enhanced waste heat recovery system operated by hot chimney flue gases from a cement plant is designed, analyzed, and evaluated. The configuration of the system is competitive and innovative. It is designed to be capable of producing space air cooling and electricity generation, simultaneously. Three temperature levels in the proposed cycle are considered, and a detailed mathematical model is developed with energy, exergy, and economic aspects are considered to achieve the best performance of the system. Computer FORTRAN subroutines are developed and run for simulation of several scenarios. A comprehensive parametric investigation and thermo-economic analysis are conducted and presented. It was found that the optimistic recovery system can achieve a refrigeration load coverage of 300 kW, while the energy and exergy efficiencies are 36.23% and 29.41%, respectively. The anticipated system seems to be optimistic knowing the cost of the product is estimated to be $45.97 per GJ.

“…Waste heat is a by-product in any thermal process which is dissipated unused in the environment. Despite having a lower exergy, waste heat recovery, in recent years, has been in spot-light for the improvement it brings to the system efficiency and the gains in terms of pollution reduction (Nag et al 2018;Shu et al 2018;Muralidhar et al 2018;Nour Eddine et al 2018;Thacher et al 2007;Deng et al 2013;Liu et al 2016;Orr et al 2016;Omer et al 2020;Angeline et al 2019).…”

This study aims at energy harvesting mufflers that utilize thermoelectric generators (TEG) to convert waste heat from the engine exhaust into electricity and simultaneously reduce engine noise. The recovered electricity can be used to power the auxiliary units in the automobile and can effectively improve the overall efficiency of the system. In this study, an automotive exhaust thermoelectric generator (AETEG) unit is fabricated to extract the waste exhaust heat from the engine. To further enhance the performance of AETEG unit, changes in the internal geometry of the unit are proposed, and a systematic computational study is carried. Investigation results indicate that transformations in the internal geometry enhance the heat transfer rate due to lower flow stratification and induced turbulence. This shows increasing potential for higher electricity generation. However, an increase in backpressure due to flow obstruction remains a problem with increasing baffle count. The internal geometry with six baffles gave the best thermal performance with backpressure within acceptable limits for the studied cases. Additionally, that AETEG unit serves as a noise muffler and attenuates the exhaust noise by 53 dBA.
