【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.更多还原

【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.更多还原
