Study of the Effect of Magnetic Field and Pulsating Flow on the Thermoelectric Cooler Performance Using Fuzzy Logic Control

Abstract

A forced convective pulsating flow of the air and magnetic field effect on the thermoelectric cooler performance is experimentally investigated. The experimental tests are conducted at a constant flow rate with Reynolds number of 5871. The applied electric power, magnetic field, pulsation rate and the output temperatures for both TEC sides are recorded and manipulated to evaluate the coefficient of the performance (COP) of the TEC. The obtained temperature differences are between 5.56 °C and 19.8 °C. TEC’s COPc ranges from 0.122 to 0.277. The optimum COP of 0.277 during these experimental tests occurred at 52.247 W input power, magnetic field of 1.25 T, and 41.28 Womersley number. Comparing with Fuzzy logic results it shows a good agreement (T; Tesla).
