摘要

摘要: 微极流体薄膜层通过按滑移速度移动的可渗透无限竖直平板时，研究热辐射对混合对流薄膜层流动和热传导的影响．假定流体粘度和热传导率变化是温度的一个函数．对一些典型的可变参数值，应用Chebyshev谱方法，数值求解流动的控制方程．将所得结果与已发表文献的结果进行比较，结果是一致的．绘出并讨论了可变参数对速度、微旋转速度、温度分布曲线、表面摩擦因数和Nusselt数的影响．

Abstract: The influence of thermal radiation on the problem of mixed convection thin film flow and heat transfer of a micropolar fluid past a moving infinite vertical porous flat plate with slip velocity was dealt with. The fluid viscosity and the thermal conductivity were assumed to vary as a function of temperature. The equations governing the flow were solved numerically using the Chebyshev spectral method for some representative value of various parameters. Comparisons with previously published work were performed and found to be in an excellent agreement. The effects of various parameters on the velocity, the microrotation velocity and the temperature profiles as well as the skinfriction coefficient and the Nusselt number were plotted and discussed.
