چکیده
Contact thermal resistance is an important indicator of the efficiency heat transfer between contact interfaces.The interfaces superalloy GH4169 in high temperature was investigated byusing ANSYS. The real surface morphology obtained with optical microscope, and its modelwas reconstructed Based on theory structural mechanics, elastoplastic deformation microstructure interface simulated, analyzed contactinterfaces. effect radiative studied.At same time, impact radiation considered.Finally, it tested by using experimental test device. result show that maximum deviation thecontact 12.60%, betweensuperalloy decreases increase pressure; interfacetemperature difference increases first then temperature.

Numerical simulation of high-temperature thermal contact resistance and its reduction mechanism
High-temperature thermal contact resistance (TCR) plays an important role in heat-pipe-cooled thermal protection structures due to the existence of contact interface between the embedded heat pipe and the heat resistive structure, and the reduction mechanism of thermal contact resistance is of special interests in the design of such structures. The present paper proposed a finite element model ...
