将高阶理论推广到三维情况,采用界面平均温度代替温度函数中待定系数作为未知量,并取消了亚子胞的概念,减少了求解方程数量,有效地提高了计算效率.在单胞的热分析过程中,利用热流与平均温度之间的关系建立子胞热传导方程,进行温度场求解,并与有限元法计算结果进行了比较,验证了该方法的正确性和有效性.
The high-order theory is generalized to the three-dimensional case, the interface average temperature is used to replace the undetermined coefficient in the temperature function as the unknown quantity, the concept of sub-sub-cell is canceled, the number of solving equations is reduced and the computational efficiency is effectively improved. In the process of analysis, the heat conduction equation and the average temperature were used to establish the heat conduction equation of the daughter cell. The temperature field was solved and compared with the result of the finite element method. The correctness and validity of the method were verified.
