综述了CFD模拟重气扩散过程复杂障碍物产生湍流效应的评估模型。κ-ε模型虽有缺陷但仍可为其它模型提供初始速度场,Realizableκ-ε模型和显式代数应力模型(EASM)具有应用前景,大涡模拟则可以在需要了解小尺度信息同时计算资源足够丰富的时候尝试使用。
The evaluation model of the turbulent effect of complex obstacles in CFD simulation of heavy gas diffusion process is reviewed. Although the κ-ε model has some shortcomings, it can still provide the initial velocity field for other models. The Realizable κ-ε model and the explicit algebraic stress model (EASM) have potential applications. Large-eddy simulation can be used when it is necessary to know the small-scale information and calculate the resources Try to use when rich.
