Experimental Validation Atotal cm2 Th (◦C) Tc (◦C) 900 516.47 139.76 To validate the analytically modelled system’s results, the thermoelectric module TEC1-12706 from Section 3.1 was used to emulate a TEG unit cell of the whole TEG system. Its effective material properties are shown in Table 3. On the experimental setup’s hot side, to mimic the exhaust gas, hot air was supplied to the test section by a hot air gun with temperature and mass flow rate maintained at 141 ◦C and 0.025 kg/s, respectively. As for the cold side, water was used to mimic the ethylene glycol. The cooling water entering the test section was maintained at a temperature of 29.5 ◦C and a mass flow rate of 0.07 kg/s throughout the test. Furthermore, an analytical model based on the experimental test inputs was carried out purposely to simulate the experiment. Figure 11 shows a comparison between the experiment and the analytical outlet temperatures for the hot and cold fluids at various electrical load resistances. As can be seen, the analytical and the experimental results at the cold side are in good agreement, with an apparent slight discrepancy for the hot side results, which was mainly due to insulation losses. The figure also presents the analytical junction’s hot and cold temperatures. A significant change in the cold junction temperature can be seen due to the change in the load resistance, which is verified by several other studies as presented by Attar et al. [21]. Furthermore, a good agreement between the experimentally obtained electrical power output results and the analytically obtained power outputs at variable load resistance is shown in Figure 12. The figure also shows the analyzed errors where the maximum noted error of the output power was 4%.PDF Image | Thermoelectric Generator (TEG) System for Automotive Exhaust
