| 摘 要： | 边界层逆压梯度作用下的流动是许多工程中的一个基础问题，由于逆压梯度作用，流动形态复杂，使得数值模拟有很大的难度。基于雷诺平均纳维‐斯托克斯RANS（Reynolds Averaged Navier‐Stokes）方程对二维平板逆压梯度边界层作数值计算研究，选取6种代表性的湍流模式，得到局部摩擦系数的数值解，与实验值比较，发现k‐ω模式具有很好的精度。基于该湍流模式，给出了湍动能分布，该结果有助于认识逆压梯度边界层流动的复杂特征。 |
| 关 键 词： | 逆压梯度边界层 RANS 湍流模式 适用性 湍动能 |

| Abstract: | Boundary layer flow with adverse pressure gradients (APG ) is a basic problem in many engineering applications .Due to APG ,the flow becomes complex and is difficult to be simulated by numerical method .In the present paper ,a numerical study of two‐dimensional boundary layer flow with APG is conducted based on Reynolds‐averaged Navier‐Stokes (RANS ) equations .Six representative turbulence models are evaluated for APG flow .By comparison of numerical local frictional resistance coefficient and experimental results ,it revealed that k‐ω model has a high precision .Meanwhile ,the turbulent kinetic energy is also studied ,which may be helpful to study the APG flow’s behavior . |
| Keywords: | boundary layer with adverse pressure gradient RANS turbulence models applicability turbulent kinetic energy |
