| Abstract: | An experimental setup of high-temperature and high-pressure thermal contact conductance(TCC) with a compensation heater is independently developed according to the material properties and working environments of aero-engine hot-end components.A pure Cu bar is used as the heat-flow meter to measure the axial heat flux,which is also suitable for superalloys whose thermal conductivity is either unclear or exhibits great variation with temperature.An experimental investigation of TCC is conducted with pressed p... |
