Taking into account the effect of viscous dissipation in the energy equation, we numerically explore the flow of an incompressible micropolar fluid with heat and mass transfer through a resistive porous medium between plane channel walls. By exploiting a similarity transformation, the governing partial differential equations are transformed into a system of nonlinear coupled ordinary differential equations, which are solved numerically for various problem parameters by means of quasi-linearization. It is found that the effect of viscous dissipation is to increase the heat and mass transfer rate at both the lower and upper walls of the channel.

多孔介质中微极性流体流动中粘性耗散的数值模拟

考虑到能量方程中的粘性耗散效应,我们在数值上探索了不可压缩的微极性流体在平面通道壁之间通过电阻性多孔介质进行传热和传质的流动。通过利用相似性变换,将控制的偏微分方程组转换为非线性耦合常微分方程组,并通过准线性化对各种问题参数进行数值求解。发现粘性耗散的效果是增加通道的下壁和上壁处的热量和传质速率。
