The development on entropy generation in fluid flows has applications in many medical equipment such as cryogenic devices and therapeutic heat apparatus. This study looks at how porous medium, multi-slips, and entropy formation affect the pumping of Jeffrey nanofluid flow through an asymmetric channel containing motile microorganims. A lubrication theory is used to neglect the fluctuation effects in the flow. Numerical simulations are utilized to generate data for specific physical features of the problem utilizing the Shooting approach on Mathematica. Following a thorough research, it is appropriate to conclude that the porous medium's permeability reduces flow speed along the walls while increases at the center of the flow region. Graphical representation of the results further reveals that entropy production can be decreased by including high thermal slip and low viscous slip elements. It is also worth noting that the Brinkman number reduces the thermal distribution in the flow while it helps in increasing the flow speed.
流体流动中熵产生的研究在许多医疗设备中都有应用，如低温装置和治疗热设备。本研究考察了多孔介质、多滑移和熵形成如何影响杰弗里纳米流体通过含有活动微生物的不对称通道的泵送。采用润滑理论忽略流动中的波动效应。利用Mathematica上的打靶法进行数值模拟，以生成该问题特定物理特征的数据。经过深入研究，可以得出结论：多孔介质的渗透率会降低沿壁面的流速，而在流动区域中心流速会增加。结果的图形表示进一步表明，通过包含高热滑移和低粘性滑移元素可以降低熵产生。还值得注意的是，布林克曼数会降低流动中的热分布，同时有助于提高流速。
