Thermal analysis of the BD contact surface by powered the TS using a thermoelectric generators (TEG)

This paper aims to use the heat energy generated during braking; TSs work from thermal energy converted into electrical energy. A thermoelectric generator consisting of semiconductor generator modules is used to master the concept of electricity generation. In a semiconductor thermoelectric power module, thermal energy is converted into electrical energy and stored in a battery. A thermoelectric open-circuit (OC) output voltage (OV) is designed to serve as a bridge between the thermoelectric generator and the temperature measuring sensor. The BD’s thermal conductivity (ThC) and TEG output power and efficiency are also discussed. The general expressions of power and ability of the generator under internally and externally irreversible model are derived. The results showed that, power output to the TS and efficiency of the TEG increased with the disc thermal conductance.
