激光辐照金属/炸药复合介质温度场的数值模拟
-
摘要: 当激光辐照金属/炸药复合介质外表面时，在变物性及界面有接触热阻的条件下，用二维线性瞬态导焓方程，数值计算了介质内部温度场时空分布。作为特例，将常物性及无接触热阻下的数值解与相同条件下的二维线性瞬态导热方程的解析解相比较，结果表明数值法的计算程序及结果是可信的。Abstract: The planar non-linear instantaneous enthalph equation is used to numerically compute the inside temperature distribution of complex medium meatal/ explosive materials with varied thermophysical properties and contact thermal resistance when the surface irradiated by laser. The comparisons of numerical simulation with the analytical results show they are close on the same conditions.
