摘要
考虑热量传播速度这一个因素,利用拉普拉斯变换对冲击加热半无限物体的瞬态导热方程进行了理论求解,并以V_2A18%C_r.8%Ni材料为例做了具体计算;针对热量传播速度对温度的影响做了物理方面的分析和讨论.结果表明在某些场合,考虑热量传播速度这一因素是非常必要的.
This paper solves the transient conduction equation of thermal shock semi-infinite object by Laplace transform and takes the factor of heat propagation velocity into account.To aim at the effect of heat propagation velocity on the temperature we make detailed calculation with material V2A18%Cr.8%Ni and make physical analysis as well as discussion.The results show that it is essential to consider the factor of heat propagation velocity.
