包套中铝棒端面受热过程中内部温度场的数值模拟

Numerical Simulation of Internal Temperature Field during Heating on End Face of Aluminum Rod in Wrap

研究第一类边界条件下半无限大物体的非稳态导热问题,主要是通过建立内部温度场来分析受热过程物体的不同位置x的温度T随时间τ的变化关系,其中还需考虑是否有相变以及相界移动的情况。

For researching the unsteady state heat conduction to the semi-infinite objects under the first kind boundary condition,the change relationship of the temperature T at different positions x with the timeτ as the object is heating is analyzed mainly by establishing the internal temperature field,in which mnst be consider whether have a phase transition and movment of phase boundary.
