平面叶栅涡轮的CFD建模问题及解决方法

Problem of CFD modeling for plane cascade turbine and solving method

针对FLUENT的前处理软件GAMBIT,研究了平面叶栅涡轮的CFD建模方法。通过分析常规建模可能存在的缺陷和不能生成所需模型的原因,提出了平面叶栅建模的正确步骤。实践表明,该方法是可行的,并能够提高计算模型的精度,从而为涡轮机械的内流场建模问题提供解决途径。

This paper discusses the modeling of plane cascade turbine on workbench GAMBIT as a pre-proceeding software of FLUENT. By analyzing drawbacks and failure which made in the conventional modeling, a kind of reasonable modeling method for the problem is provided. The practice shows that the modeling precision is improved and the method is good for modeling of the similar turbo machinery.
