湍流的特征
湍流本质是非稳态的、三维的、非周期的漩涡运动(脉动)的,湍流会加强混合节选段落二:
Fluent Inc. offers several state-of-the-art turbulence modeling options that provide the accuracy that engineers need at reasonable computational expense. These turbulence models include the two-equation and RSM models.节选段落三:
We have described the turbulence models and near-wall treatments available in Fluent CFD software and have tried to show how successful modeling of turbulent flows requires engineering judgement.
