摘要温度场是数值模拟中重要的研究参数,采用普遍使用的有限容积法,推导了三文稳态与非稳态温度场导热通用控制方程的离散过程。网格划分采用均匀规则网格,迭代计算采用了高斯赛德尔迭代法。利用Fortran语言编程,实现了三文瞬态与非稳态的导热温度场的通用计算程序。给出不同边界条件下的仿真设计算法,并针对不同边界条件举例在Fluent中验证。程序在稳态中符合的很好,非稳态中有少许误差。19282

Title Research on the three dimensional transient
temperature field simulation algorithm
Abstract
Concentrating on important research field, temperature field, this paper
makes a research on the general control equations’ dissertation
progress of two dimensional and three dimensional temperature field. In
the grid pision part, this paper use uniform and regular grids. In
the iteration part, this paper use Gauss-Seidel iterative method. Make
a general computation program by Fortran language and realize the
ability that can be used to compute the steady and unsteady three
dimensional heat transfer temperature field. This paper gives the
different simulation algorithm under different boundary conditions.
Verify the correctness through comparison with the computation results
of Fluent. The conclusion shows that the results of the program fit
well with the results of Fluent.
