Heat Conduction in a Thin Film which Reflects Size and Memory Effects Induced by an Ultra-Fast Laser

Abstract:

An improved heat conduction model which reflects size and memory effects based on the CV model is proposed to simulate a one-dimensional thermal transport problem in a thin film induced by the ultra-fast laser. The results show that a thermal wave effect is appeared in heat conduction. We find that for the improved CV model in this work a larger Knudsen number will lead to a higher temperature. Although the improved CV model and the CV model lead to the similar thermal wave behavior, the thermal wave speeds for the two models are different.
