Abstract
Thermoelectric generator (TEG) for power generation system is proposed for energy recovery. The heat from cooling scramjet would be converted to electric energy. A parametric study of TEGs power generation system for heat recovery has been performed. The output power, the efficiency and the fuel flow saving ratio of the system have been analyzed and the proposed heat transfer analysis method of the system is depicted. Numerical results indicate that the total output power, the efficiency and the fuel flow saving ratio increase with the increase of fuel coolant flow rate. Most important, valuable amount of output power can be drawn by employing TEGs power generation system for hypersonic vehicles powered by scramjet.
