A novel mathematical analysis is established that summits the key features of Cilia propulsion for a non-Newtonian Couple Stress fluid with the electroosmosis and heat transfer. In such physiological models, the conduit may have a symmetric or asymmetric configuration in accordance with the biological problem. Being mindful of this fact, we have disclosed an integrated analysis on symmetric in addition to asymmetric conduits that incorporates major physiological applications. The creeping flow inference is reviewed to model this realistic problem and exact solutions are computed for both the conduit cases. Graphical illustrations are unveiled to highlight the physical aspects of cilia propulsion on symmetric in addition to asymmetric conduit and an inclusive comparison study is conveyed. The flow profile attains higher values for an asymmetric conduit in relation to the symmetric. Likewise, the pressure rise and pressure gradient also score high for asymmetric conduit in relation to the symmetric conduit. A visual representation of flow inside symmetric as well as asymmetric conduit is provided by streamline graphs and temperature profile as well.
建立了一种新颖的数学分析方法，该方法总结了具有电渗和热传递的非牛顿 couple stress 流体的纤毛推进的关键特征。在这种生理模型中，根据生物学问题，管道可能具有对称或不对称的结构。考虑到这一事实，我们除了对不对称管道进行综合分析外，还对对称管道进行了综合分析，其中纳入了主要的生理应用。回顾了蠕动流推理以对这个实际问题进行建模，并针对两种管道情况计算了精确解。展示了图形说明，以突出对称和不对称管道上纤毛推进的物理方面，并进行了全面的比较研究。与对称管道相比，不对称管道的流动剖面具有更高的值。同样，与对称管道相比，不对称管道的压力上升和压力梯度也更高。流线图和温度剖面也提供了对称和不对称管道内流动的可视化表示。
