| 摘 要： | 针对层流流动,提出了一个新的指数型速度分布方程。将其代入karman边界层动量方程后,求得的边界层厚度、边界层中任意点的流速、平板壁面上的总曳力及曳力系数均与Basius精确解极为接近。

| Abstract: | This paper proposes a new model of exponential velocity profile equation for laminar flow. The thickness of the boundary layer, the velocity at any point within the layer and the total drag force acting on the plate wall can be determined by substituting the equation into karman' s boundary layer momentum equation. The results arc very close to the Blasius exact results. |
