| 摘 要： | 为了研究竖壁自然对流换热的特点,将边界层的控制方程转化为相似方程.在此基础上,进一步采用引入中间变量的方法,将相似方程转化为五个常微分方程.运用MATLAB对相似解进行数值模拟,获得了层流边界层内速度和温度的分布特点,同时,得到了与其相关的其它物理量的变化规律.

| Abstract: | The attempt to investigate the feature of natural heat convection involves transforming control equations in boundary layer into approximate equations.Based on this method,approximate equations become five ordinary differential equations by introducing indirect variables.Adopting MATLAB for numerical simulation of the approximate solutions renders possible not only the feature of distribution of temperature and velocity in boundary layer of laminar flow,but also the changing rules of other quantities of phy... |
