Electrokinetic peristaltic slip transport in an asymmetric porous microchannel is studied to explore the entropy production in steady magnetohydrodynamic Jeffery fluid under simulation of Debye and long-wavelength approximations. The emerging two-dimensional bounded problem with electrokinetic body forces is solved numerically. Appropriate combination of heat and momentum equations with Jeffery model, after non-dimensionalization, generated controlling parameters in order to determine velocity, pressure gradient, temperature, entropy production and Bejan number. The trapping mechanism is also visualized by drawing streamlines against governing parameters. The zeta potential signifies the flow and heat response of the system. Former parameters like Brinkman number and Joule heating are compatibly liable for the increase in thermal irreversibilities. The outcomes of the present analysis are applicable in designing the thermofluidic micropumps and biomicrofluidic devices for separation processes and diagnosis.

研究了不对称多孔微通道中的电动蠕动滑移输运，以研究在Debye和长波近似作用下稳定磁流体动力学Jeffery流体的熵产。用数值方法解决了新兴的带有电动体力的二维有界问题。在对热和动量方程与Jeffery模型进行适当组合后，进行了无量纲化后，生成了控制参数，以确定速度，压力梯度，温度，熵产生和Bejan数。通过绘制针对控制参数的流线，还可以使捕获机制可视化。ζ电位表示系统的流量和热响应。像布林克曼数和焦耳热这样的前参数对热不可逆性的增加负有赔偿责任。
