| 摘 要： | 根据模仿权残法的思想,用积分方程近似求解零攻角平板边界层层流问题。在满足四个基本边界层条件的基础上,推出改进的平板边界层的近似速度分布多项式。其对应的摩擦阻力计算公式与精确解完全相同。同时,该多项式对应的曲线与精确解的速度分布曲线拟合很好。

| Abstract: | By using the integration method,it is sought to solve the problem for laminar boundary layer on a flat plate at zero incidence.The improvement on approximation velocity polynomial was derived available to satisfy four basic boundary conditions.Its corresponding formula for calculating the drop on a flat plate shows the identity with the exact solution.Also,the curve plotted accordion to the polynomial shows in good agreement with the velocity distribution profile given by the exact solution. |
