放置竖直孤立平板的二维围场内的空气流动与换热的数值分析

针对内部放置孤立平板的二维围场内的空气流动与换热问题,在稳态、常物性和壁面温度以及孤立平板温度恒定的条件下,采用SIM PLER算法,对围场内部的空气进行了流动与换热的数值模拟计算。在瑞利数Ra=10000时,计算得到了二维围场内的流线、等温线以及热线。

In order to investigate the fluxion and heat transfer of air in a 2 D square enclosure with an isolated plate.SIMPLER algorithm was adopted based on the Reylonds conservation equations of the steady-state constant property laminar flow and a constant temperature of the isolated plate and the inner walls of the enclosure condition.Slove fluid velocity and temperature fields inthe enclosure for Ra=10000,and draw the diagrams of stream lines,isotherms and heat lines.
