| 摘 要： | 对一个旋转盘腔的流场进行了数值计算研究。该盘腔由一个旋转盘,一个静止盘及静止的外围屏组成。在盘腔的核心区采用标准k-ε模型,在近壁区分别采用了两种低雷诺数紊流模型,即(1)单方程模型和(2)Launder-Sharma低雷诺数k-ε模型,并且在第二个模型中考虑了固体旋转引起的耗散率降低的修正。

| Abstract: | The flow inside an enclosed rotor-stator disc cavity was studiednumerically.The disc cavity was composed of a rotating disc,a stationary disc and a stationary shroud.The standard k-ε turbulence model was employed in the core region of the cavity.Two low Reynolds number turbulence models,single equation model and Launder-Sharma Low Reynolds number k-ε model,were used in the near wall region.The modification of dissipation rate decrease caused by solid body rotation was considered in the second model.The results showed that Launder-Sharma low Reynolds k-ε model could more accurately reproduce the experimental data than the single equation model. |
