Abstract

A finite element numerical simulation is undertaken to explore the aspects of angled magnetic field and thermo-diffusion on an unsteady reacting mixed convection flow of hydro-magnetic Casson dissipating fluid with thermal radiation. The fluid streams across an oscillating tilted plate ingrained in a porous medium including time altering temperature and concentration. The dimensionless flow guiding partial differential equations along their associated initial and boundary conditions are handled enforcing an efficient finite element scheme. The key parameters affecting the velocity, temperature, and concentration profiles are comprehensively interpreted through graphical representations while the skin friction, heat transfer, and mass transfer rates outlined via tables. The ultimate results of this study posted that the plate inclination angle, Casson parameter, and applied magnetic strengths are compelled to impede the fluid velocity and local skin friction whereas the porosity parameter displays a reverse effect. The thermo-diffusion effect amplifies the fluid velocity and species concentration. It also supported that the Eckert number and heat source boost up the velocity and temperature profiles. Moreover, increasing radiation parameter and time crusade an upsurge the Nusselt number. The chemical reaction quickens the Sherwood number but it decays with the thermo-diffusion parameter. A comparative analysis between the current findings and existing research works in the literature demonstrates the results’ precision and exactitude.
斜磁场作用下反应和耗散流体沿振荡斜多孔板的非定常混合对流流体磁卡森热扩散流动
采用有限元数值模拟方法,探讨了带热辐射的磁磁卡森耗散流体非定常反应混合对流的角度磁场和热扩散问题。流体流过嵌入多孔介质中的振荡倾斜板,其中包括随时间变化的温度和浓度。采用有效的有限元格式处理了无量纲导流偏微分方程及其相关的初始条件和边界条件。影响速度、温度和浓度分布的关键参数通过图形表示全面解释,而表面摩擦、传热和传质率通过表格概述。本研究的最终结果表明,板倾角、卡森参数和外加磁场强度会影响流体速度和局部表面摩擦,而孔隙度参数则会影响流体速度和局部表面摩擦。热扩散效应放大了流体速度和物质浓度。它还支持埃克特数和热源提高速度和温度分布。此外,随着辐射参数和时间的增加,努塞尔数急剧增加。化学反应使舍伍德数加快,但随热扩散参数的增大而衰减。通过与文献中已有研究成果的对比分析,证明了所得结果的准确性和准确性。
