Mixed Convection Flow in a Vertical Channel With Boundary Conditions of the Third Kind in the Presence of Heat Source/Sink

  • 摘要: 在竖向平行板通道中,研究粘性耗散和热源/热汇对充分发展的混合层状对流的影响.平板与外部流体进行了热交换,考虑了两种边界条件:与外部流体的参考温度相同的和不相同的.首先,数值地求解Brinkman数或Grashof数可以忽略的简单情况,然后,运用摄动级数法分析有热源/热汇存在时,浮力和粘性耗散对流动的组合影响,并证明摄动参数不大时是有效的.为了放宽摄动参数的使用条件,运用4阶Runge-Kutta打靶法,求解速度和温度场,对平板处的速度、温度、表面摩擦和Nusselt数进行数值讨论并绘出图形.
