Blasius方程中临界值的分析估计

Analytic Estimation of the Critical Value Arising in Blasius Equation

证明了流体力学边界层理论中著名的Blasius方程的一个新性质,它在二维平板流的研究中具有重要的作用,由此建立它的积分形式,并给出方程中的临界值βc的分析估计。

In this paper, we prove a new property on the well-known Blasius equation, which arises from the boundary layer theory in fluid mechanics and is of great importance in the two-dimensional laminar viscous flow on a semiinfinite flat plate. Based it, we obtain the integral form of the Blasius equation and the analytic estimation of critical valueβc.
