采用任意拉格朗日—欧拉 (ALE)框架下的有限体积法对平展流湍流输运特性进行了数值模拟研究。根据平展流特征对湍流模拟的k ε模型进行了修正 ,并对计算网格的生成进行了探讨 ,在此基础上分析了旋流强度对平展流输运特性的影响以及两个平行平展流间的相互作用。
The finite volume method under the arbitrary Lagrange - Euler (ALE) framework is used to simulate the turbulent transport of flat flow. The k ε model of turbulent simulation is modified according to the characteristics of flat flow and the formation of computational grid is discussed. Based on the analysis, the influence of swirling flow on the transport characteristics of flat flow and the influence of two parallel flat flow Interaction.
