摘要

本文介绍了一种新的方法来评估Soret和Dufour对垂直倾斜多孔振荡板上粘性耗散磁流的影响,考虑了化学反应,热源和热辐射。该研究独特地结合了通过摇摆倾斜多孔板的流动,具有不同磁场倾角的磁流体流动,以及粘性耗散和Dufour和Soret效应的相互作用。将模型的非线性流动管理维偏微分方程更新为非线性无量纲偏微分方程,并采用有效的有限元技术进行求解。根据模型中最重要的相关参数,以图形化的方式分析了速度、温度和浓度分布,并利用MATLAB软件基于数值解对地表表数据进行了表面摩擦、热量和质量输运率的计算。结果表明,较高的粘性耗散、热源、渗透率以及Soret和Dufour参数扩大了速度分布。由于辐射、磁场强度、板倾角和对向磁场的影响,在速度分布上实现了相反的导电性。热引起粘滞耗散,触发杜福效应使温度分布扩大,但随热辐射而减小。浓度场受时间因子和索雷特效应的影响而持续,但受化学反应的影响而衰减。此外,磁导率参数改善了表面摩擦,而板倾角和专用磁场强度阻碍了表面摩擦。传质速率随化学过程而增大,随热扩散而减小。传热速率随时间和热辐射条件的变化而增大。相当重要的是,将这些不同的物理参数整合到一个单一的数值研究中,为它们对流场的综合影响提供了新的见解,有助于提高对多孔介质中各种影响下的磁流体流动性能的认识。最后,通过与以往研究的比较,验证了研究结果的准确性和准确性。

A Numerical Approach of Hydromagnetic Flow Past Magnetic Field Inclination Wavering Tilted Porous Plate With Dufour and Soret Effects

The present article introduces a novel approach to evaluate the effects of Soret and Dufour on viscous dissipating hydromagnetic flow over the vertically tilted porous oscillating plate, considering chemical reaction, heat sources, and thermal radiation. The study uniquely combines flow past a wavering tilted porous plate, hydromagnetic flow with varying magnetic field inclinations, and the interplay of viscous dissipation and the Dufour and Soret effects. The model's nonlinear flow managerial dimensional PDEs were renewed into nonlinear dimensionless PDEs and solved using an effective finite element technique. The velocity, temperature, and concentration distributions are analyzed graphically counter to the most significant pertinent parameters of the model, and the skin friction, heat, and mass conveyance rates are deliberated by the tabular data at the surface using MATLAB software based on numerical solutions. The results depicted that higher viscous dissipation, heat source, permeability, and Soret and Dufour parameters expand the velocity distribution. The opposite conduct was realized in the velocity distribution due to the radiation, magnetic field strength, plate inclination angle, and aligned magnetic field. The heat causes viscous dissipation, and Dufour effects are triggered to enlarge temperature distribution, but it drops with thermal radiation. The concentration field is sustained by the time factor and the Soret effect but decays with the influence of chemical reactions. Further, the skin friction improved at the surface by the permeability parameter, while the plate tilt angle and devoted magnetic strengths hindered the skin friction. The mass transfer rate grows with chemical processes but decreases with thermo-diffusion. The heat transfer rate grows at the surface with time and thermal radiation conditions. Considerably, integrating these diverse physical parameters in a single numerical study provides new insights into their combined effects on flow fields, contributing to advancing the knowledge of the hydromagnetic fluid flow performance under various influences in the porous media. Finally, a comparative examination with previous studies validated the precision and exactness of the findings.
