| 摘 要： | 基于普朗特的边界层思想,以不可简化成稀相的风沙流体为研究对象,以风沙流的一般方程为基础,在基本假设的条件下,建立了高速轿车车身顶部过流表面的边界层微分方程并给出沙流在近壁表面以滑移为特征的边界条件。又考虑到固体颗粒对边界层的扰动作用,引入了扰动因子。通过对边界层厚度的积分并利用相关条件,得到了边界层动量积分方程。

| Abstract: | On the basis of Prantel boundary layer idea, wind sand fluid of irreducible rare phase as research object, by the foundation of general equation of wind sand fluid, in the condition of basic hypothesis, the boundary layer equation of car roof surface is set up and the boundary condition the fluid slippage character in solid wall surface is given. Also, considering the disturbance action of solid grain to boundary layer, disturbance factor is cited. By the integral to boundary layer thickness and relative conditions, the momentum integral equation of boundary layer is obtained. |
