在低雷诺数和长波长的假设下，研究了电渗流、辐射、焦耳热对切双曲流体在内窥镜中蠕动运动的影响。在两个同轴管之间，考虑圆柱形的非牛顿双曲正切流体。采用Helmholtz-Smoluchowski模型描述电渗过程。将同伦摄动技术应用于非线性偏微分方程的求解。以图形方式描述了各种物理参数对速度、温度、生热系数和表面摩擦系数的影响。本研究的显著结果是，电渗参数的影响在前半部分减小，然后增强电渗参数的正值的速度剖面。焦耳加热增强了温度分布，而哈特曼数和热辐射降低了传热速率。同时，达西数的增加也提高了表面摩擦系数.本研究可应用于生物微流控技术中，以调节微通道中的流体流动，并研究生物医学中的癌症肿瘤消除和动脉阻塞治疗。
The current study explores the impact of electro-osmotic flow, radiation, Joule heating through porous medium on the peristaltic motion of tangent hyperbolic fluid in an endoscope with the assumptions of low Reynolds number and long wavelength. Between two coaxial tubes, a non-Newtonian hyperbolic tangent fluid is considered in cylindrical form. The Helmholtz–Smoluchowski model is used to describe the electroosmosis processes. The Homotopy Perturbation technique (HPM) is imposed to deal the equations of nonlinear partial differential equations. The impact of various physical parameters on velocity, temperature, heat generation coefficient, and coefficient of skin friction were graphically depicted. The significant outcome of the present study is that the impact of the electro-osmotic parameter in the first half diminishes and then enhances the velocity profile for the positive value of electroosmosis parameter. Joule heating enhances the temperature profile whereas Hartmann number and thermal radiation diminish the rate of heat transfer. And also, Darcy number enhances the skin friction coefficient. The present study can be applicable in the bio microfluidics to regulate fluid flow through microchannels and also examining the cancer tumour elimination and artery blockage treatment in biomedical.
