摘要
1 基本方程及解法运动方程和能量方程为式中,β为体膨胀系数;K为导热系数;T_e是边界层外的温度.边界条件为y=0,u=v=0,T=T_w;y=∞,u=0,T=T_e.
This paper presents a numerical computation for vertical heating of the temperature boundary layer outside a flat plate under free convection. The two-point boundary value problem is transformed into an initial value one for the estimation of the initial values (0) and (0). The four-step Lunge-Kutta integral method and Naqishem-Swikt iteration method were used in the calculation.
