Parametric study of an integrated thermoelectric generation thermal management system for hypersonic vehicle

An integrated thermoelectric generation thermal management system (TEG-TMS) for a regenerative cooling scramjet is proposed. Thermoelectric power generators are integrated in the scramjet structure. The TEG-TMS will reduce the fuel flux for cooling, through converting part of the energy by heat conduction on the scramjet structure to electric power. It will decrease the heat that must be taken away by fuel and the fuel cooling capacity is indirectly increased. At the same time, high temperature and high pressure fuel also has the capacity for doing work. It will flow through a turbine and get additional power output for hypersonic vehicle using. A parametric study of the integrated TEG-TMS for scramjet has been performed. It is known through performance analyses that integrated thermoelectric generation thermal management system has excellent potential performance over conventional regenerative cooling. The fuel flux will be reduced while the TEG-TMS would give power output.
