Eng. 2006;128(4): doi: / Figure Legend: Predicted surface thermal response of a 1.4-mm-thick aluminum shell in contact with a stainless steel hot station. The dimensionless temperature, T̃s, is defined as T̃s(t)=[Ts(t)−Ti]∕(Th−Ti), where Ti and Th are the initial temperatures of the shell mold and the hot station, respectively. The interfacial conductance, h, varies from 500W∕m2K to infinity. An experimental thermal response with an aluminum shell at the same thickness is included for comparison. The simulation result agrees well with the experimental one with h≈3000W∕m2K.
