热幅射对抽吸或喷射三维Couette流温度分布的影响

Radiation Effect on Temperature Distribution in Three-Dimensional Couette Flow With Suction or Injection

在固定的底板上有横向正弦射流,而匀速运动的多孔介质顶板以常速率完全抽出的情况下,理论分析了热幅射对三维Couette流动温度分布的影响.在这种射流速度下,流动呈现三维流动.利用图形分析了Prandtl数、幅射参数和射流参数对传热速率的影响.Prandtl数对温度分布的影响比射流参数或幅射参数大得多.

A theoretical analysis of three-dimensional Couette flow with radiation effect on temperature distribution has been analyszed, when the injection of the fluid at the lower stationary plate is transverse sinusoidal one and its corresponding removal by constant suction through the upper porous plate in uniform motion. Due to this type of injection velocity the flow becomes three-dimensional. The effect of Prandtl number, radiation parameter and injection parameter on rate of heat transfer were examined with the help of graphs. The Prandtl number has a much greater effect on the temperature distribution than the injection or radiation parameters.
