摘要
计及超快速加热引起传热过程的非傅立叶效应,建立了第二类边界条件下的半无限体的动态温度场方程组。用拉普拉斯变换法对方程进行求解;结果表明,强热流快速加热在半无限体内产生一个温度波。波面通过之处引起局域温度突然升高。
Considering the non-Fourier effects in the course of the extremely high rate heating, the dynamic equation groups of the temperature for the half infinite body bearing heat flux are solved by the Laplace transfer method.The results indicate that the temperature wave exist during the super high rate heating.While the wave passing the place,the local temperature gets a step response suddenly.
