Thermoelectric Generator Aplication and Flow Analysis for Diesel Engine Exhaust System

27804

In this study, A prototype has been developed as the working principle of thermoelectric generators. The exhaust system of a diesel engine used for the surface will be heated and as a result of operation of the engine profit by heat energy of the exhaust gases. Required cooling effect in the occur of the different temperature of thermoelectric modules (TEM) is realised by an cooling system without engine. Reguired electric power of this system is 20 Watt as instant. Electrically are connected as series with each other thermoelectric modules realised assembly octagonal structure consisted from the aluminum 6160 material. The maximum electrical output power produce of the thermoelectric Generation (TEG) system is registered as 156.7 Watt at the 3500 rpm and 100 Nm as of the engine working condition. The discharged battery charging is performed with electrical power supplied to DC / DC converter. Then in the system, heat‐flow analysis was realised with the help Fluent which contained in the Ansys Workbench 12.0 and in the same time meaning Computational Fluid Dynamics (CFD) software.
