Abstract

The study investigates the heat and mass transfer of mixed peristaltic Casson fluid flow through a porous medium in the presence of electroosmosis. It uses the lubrication LWL-LRN analytical technique to transform flow-control equations into ordinary differential equations. The equation is simplified using a numerical solver, bvp4c, in MATLAB software. The study analyses the behaviour of momentum, thermal, solutal, and nanoparticle concentration using parameters such as the magnetic field parameter, porous, electroosmotic, Prandtl, thermal Grashof number, and solutal concentration. Comparing this work with the existing investigation reveals a high level of concordance regarding the impact of thermophoresis and Brownian variables on momentum fields. The study’s novelty is the double-diffusive effects of Casson fluid, which provides a more accurate characterisation of its flow behaviour with convective boundary conditions over an inclined surface. Such observations are useful in real-life applications to capture the shear and stress-thinning properties and flow of synovial fluid in joints, as well as to understand blood flow in several physiological conditions.

卡松流体双扩散混合对流中的传热和传质：生物医学应用

本研究探讨了存在电渗的多孔介质中卡逊混合蠕动流体流动的传热和传质问题。它使用润滑 LWL-LRN 分析技术将流量控制方程转化为常微分方程。利用 MATLAB 软件中的数值求解器 bvp4c 对方程进行了简化。研究利用磁场参数、多孔、电渗、普朗特、热格拉肖夫数和溶质浓度等参数分析了动量、热、溶质和纳米粒子浓度的行为。将这项工作与现有研究进行比较后发现，热泳和布朗变量对动量场的影响具有高度一致性。这项研究的新颖之处在于卡松流体的双重扩散效应，这为其在倾斜表面对流边界条件下的流动行为提供了更准确的描述。这种观察结果在实际应用中非常有用，可用于捕捉关节中滑膜液的剪切和应力稀化特性和流动，以及了解几种生理条件下的血流。
