| 摘 要： | 利用CFD软件对方腔的温度场和速度场进行了数值模拟计算。采用有限元法对模型的连续性方程、动量方程和能量方程进行离散。对方腔内的流体受迫对流换热进行数值模拟,主要分析了方腔顶部流体在不同速度的情况下,对方腔内部流体的温度场和速度场以及对流换热量的影响,结果表明随着方腔顶部流速的增大方腔底部的温度场和换热量也增大。

| Abstract: | Computational Fluid Dynamics(CFD) software is used to simulate the chamber’s temperature and velocity field.This CFD software is based on Finite Volume Method,and the contiruiity equation,momentum and energy equations are discredited at each finite volume.The temperature and velocity field is analyzed by varying the inlet velocity at the top of the cavity.The results show that the velocity change at the top of the cavity has bigger effect on temperature and velocity field in the cavity,especially effected the temperature and heat transfer at the bottom of the cavity. |
