Energy Conversion Efficiency of the Advanced Thermocouples Under The Influence of Applied Electric Field

This research work reports about the energy conversion characteristics of advanced thermoelectric materials like Platinum, Rhodium, Constantan, Chromel and Alumel (of types B, E, R, K and S) in the influence of applied electric field dynamics. These kinds of the materials are generally taken as the temperature measuring tools in the critical molten states of certain materials and other high temperature conditions. But here, their response only to Seebeck effect is analyzed as the functioning of thermo generator elements. This is an approach of their use in those conditions where the waste heat is available along with the electric fields. The generation of thermo emf is investigated in the normal mode to the temperature range of 330°C and then compared with their similar performances under the effect of applied electric field in various orientations (parallel and perpendicular) for different magnitudes in the same temperature range.
