Abstract

An adaptive heat flux control method which involves a variable-roughness is advanced. The shape memory alloy is attached to the cooling side-walls, and its shape is identical with the cooling side-wall when the temperature is low, but turns into artificial roughness with high temperature. The time-dependent simulation model was performed to count the unsteady heat transfer of regenerative cooling considering the Shape Memory Alloy convection. Adaptive heat flux control could reduce the wall temperature increase when the heat flux increased from 8MW/m2 to 10MW/m2. The temperature responses to the heat flux mutation tell that wider hysteresis temperature interval and lower SMA transformation temperature range are favorable for the adaptive heat flux control.
