Abstract
In this thesis, it discusses how to achieve electrical energy by using the amount of lost heat from exhaust by using (thermoelectric generators) TEG, as the use of electricity in cars is one of the most important problems in cars. This research used a motorcycle engine and also used a cooling circuit (Freon R 134A) to maintain temperature differences for the TEG, and also used a cooling fan, a water pump, a set of electrical connections and an Arduino circuit to read the results on the display screen, and all components were installed on Wheel-mounted metal frame for easy movement. This research has been directed towards the investigation of the use of TEG in the application of cars, in this paper we will discuss the design of a strategy for generating electricity through an experimental comparison made on the model and the theory in which the ANSYS program is used. Heat capacity and heat transfer are the main factors affecting the thermal performance of TEG. To achieve a uniform temperature distribution, two types of exhaust mufflers were studied using ANSYS (thermo-fluent), and SolidWorks to design the model. The first type using fins and the maximum temperature was 259.711, and by not using the fins the maximum temperature was 263.049, and the heat distribution in the second case was better than the first case. At maximum temperature, the highest voltage and current were obtained at 30V and 4.1A. Experimental and theoretical results after comparison show that the match is positive and this system can be developed and used in the automotive field on a large scale.
