摘要: 提出一种新的密度压力速度和温度耦合的算法,使用静焓方程构造温度修正量与压力修正量之间的关系,类似Rhie-Chow方法用动量方程插值,网格面上的温度压力修正量插值采用能量方程的形式.CGNS API(CFD General Notation System Application Programming Interface)作为非结构化网格求解器的前处理和后处理,基于网格的FVM(Finite Volume Method)作为偏微分方程求解方法.燃烧模拟采用Arrinius-Eddy Dissipation模型.最后给出两个算例作为说明.

关键词: 非结构网格, 有限体积法, 动量插值, 压力修正

Abstract: An algorithm with unstructured girds is introduced in which coupling of density and temperature is considered.Static enthalpy equation is employed to construct relation between temperature correction and pressure correction.As in Rhie-Chow method,temperature and pressure corrections of grid interfaces are interpolated by static enthalpy equation and omitting neighbour temperature correction as in the velocity-pressure coupling in SIMPLEC.CGNS is taken as I/O in the in-house unstructured FVM code.For combustion simulation,Arrinius-Eddy dissipation model is employed.

Key words: unstructured grid, FVM, Rhie-Chow, pressure correction
