摘要

针对不同温度脉冲进口条件对非傅立叶导热问题的影响进行了模拟,数值预示了不同脉冲形式,以及不同脉冲频率产生的不同的非傅立叶导热特征;同时也数值预示了同一种脉冲作用下,热波导热、非傅立叶导热和傅立叶扩散的差别。

Abstract

This study simulates the effects of different temperature pulse inlet conditions on non Fourier heat conduction problem, and numerically predicts different non Fourier heat conduction characters produced by different pulse types and different pulse frequencies, respectively. Also, the differences between thermal wave, non Fourier and Fourier heat conduction under the same pulse condition are showed.
