摘要
采用大型通用计算程序ＰＨＯＥＮＩＣＳ（１４版本）、并结合虚拟密度法，对有内部热源的非稳态导热与自然对流换热及辐射换热的耦合问题进行了数值求解。分析和比较了在直角坐标和贴体坐标下得到的速度场及温度场的数值模拟结果，并示出了在两种坐标下发热物质内部靠近中心处的最高温度随时间的变化趋势。
Conjugate heat transfer of transient thermal conduction,natural convection and thermal radiation with internal heat sources is simulated numerically using PHOENICS(Version 1 4) with the false density method.The flow field and temperature distribution are calculated using both the body fitted coordinates and Cartesian coordinates.The variation of the maximum temperature in the substance with internal heat sources is presented as function of the environmental temperature.
