“…Antifreeze is usually the Ethylene Glycol or Propylene Glycol which has a small amount of corrosion inhibitor. As pure water has more heat carrying capacity than just the ethylene glycol, they are mixed and it also reduces the chances of formation of rust, because when rust is circulated through the cooling system it can build sediments and reduce the cooling rate which prevents engine from cracking and sudden increase in pressure (9)(10)(11)(12).…”

A car is one of the best feats of mechanical engineering and design. A car is run by a power source that provides necessary and required energy to translate or move and the power source is an engine. During this process, there is generation as well as the exchange of heat that happens continuously to keep the car running. Over time the engine heats up, i.e. most of this chemical energy is lost to the environment as heat, which reduces the efficiency of the engine significantly. In a car, the radiator functions to monitor and regulate the engine temperature to prevent it from overheating thus improving the efficiency of the engine. A study has been made on the performance evaluation of the radiator and with the help of Ansys workbench the thermal analysis is carried out to find extreme conditions in the radiator.

“…In their study [10], the authors focused on a system where the heat source for the TEG is a hot gas flow, and the performance of the system is influenced by the flow parameters. Numerous recent papers delve into issues related to TEG application in the automotive industry, with exhaust gases used as a heat source before releasing them into the environment [11] or heat harvested from the cooling system [12]. Further efforts to enhance heat exchange by modifying the heat exchanger's geometry are discussed in [13,14].…”

This paper presents a simulation model for a system equipped with thermoelectric elements, considering the impact of independent thermal contact resistances on each side of the module. An analytical model was constructed, taking into account the asymmetry of thermal resistances between the generator/cooler and the respective heat source/heat sink. A comparative analysis of thermoelectric device operating indicators such as conducted heat, efficiency, and the electricity/cooling power produced was performed. The selection of electrical current in the circuit was analysed based on the maximization of power or efficiency. This paper discusses deviations from ideal conditions, specifically the absence of thermal resistance between the heat source/sink and the thermoelectric junction. The model accurately simulates the operating conditions of the thermoelectric system with a low computational cost. The results indicate that the total thermal resistance, rather than its location, predominantly affects the operation of the thermoelectric generator. However, in cooling operations, the influence of thermal resistance significantly depends on the cooling power demand and temperature.

Household biomass gasifier stoves (HBGSs) are used in remote areas using natural firewood that is burned in the HBGS for general purposes, such as cooking and warming in winter. The heat dissipation from the walls is assumed to be heat loss. This paper evaluates the electrical performance of thermoelectric generators (TEGs) using heat recovered from the hot walls of an HBGS, considering the effect of three primary air valve angles of 0°, 9°, and 18°. The heat recovered from the HBGS that is electrically transferred through a TEG is assessed. The results showed that the wall heat loss increases with the primary air valve angle of the HBGS. The upper zone near the HBGS gas combustion zone exhibits higher wall temperatures than the middle and lower zones, with a maximum wall temperature of 140°C resulting in an output voltage of 2.55 V. However, the middle and lower zones are also considered as their capacities are consistent with the TEG temperature range. The heat loss from the HBGS is considerably larger than that from other heat sources, and the specific heating area of the heat source is a variable that should be considered to increase the number of TEGs to achieve the desired output values for practical applications. Furthermore, this research serves as a guideline for applying TEGs to recover waste heat from various applications.
