The main objective of the present article is to conduct an entropy generation analysis on a wall-driven mixed convection copper–water nanofluid flow in an inclined channel filled with a porous medium while considering Hall effect. The permeability of the porous medium is assumed to vary exponentially across the width of the channel, while viscous dissipation and convectively heated walls are also taken into account for the flow. Various comparisons for a special case of the current model with existing literature are done, and the results are found to be in excellent agreement. Role of pertinent flow parameters on entropy generation, Bejan number, Nusselt number and skin friction are explained via plots. Movement of walls along the direction of fluid flow is prominent in generating the least amount of entropy in the system. Hall parameter has a no effect on entropy generation and skin friction. The novelty of the present investigation lies in the fact that the moving walls of the channel have been considered simultaneously with the variable permeability of the porous medium.

本文的主要目的是在考虑霍尔效应的情况下，对填充有多孔介质的倾斜通道中的壁驱动混合对流铜-水纳米流体流进行熵产生分析。假设多孔介质的渗透率在通道的整个宽度上呈指数变化，而对于流动，还考虑了粘性耗散和对流加热壁。对当前模型的特殊情况与现有文献进行了各种比较，结果非常吻合。通过曲线解释了相关流动参数在熵产生，Bejan数，Nusselt数和皮肤摩擦上的作用。壁沿流体流动方向的运动在产生系统中最小量的熵方面是突出的。霍尔参数对熵的产生和皮肤摩擦没有影响。本研究的新颖性在于，通道的活动壁与多孔介质的可变渗透率同时被考虑。
