This research delves into Maxwell fluid flow's intricate fluid dynamics, as well as heat-mass transfer features over a porous horizontal plate. The investigation encompasses magnetohydrodynamics, heat generation, radiation, chemical reactions, and the influence of activation energy. Furthermore, the study integrates slip conditions for temperature, velocity, and concentration gradients at the interface between the fluid and solid surfaces. After formulating the governing equation with the abovementioned parameters, the partial differential equations are changed into ordinary ones through a similarity revolution. The results of the bvp4c solver in MATLAB provide significant insights into how various physical parameters interact and influence the flow dynamics and heat-mass transfer characteristics. This research's primary aim and objective is to comprehensively compare plots generated for different parameters under both no-slip and slip conditions by considering fixed values as Pr The primary discoveries of this study indicate that with an increase in the power index, there is a decline in the concentration profile. In contrast, an increase in the activation energy leads to an elevation in this profile. An important revelation from this research is the significant decrease observed in the concentration profile as the activation energy parameter is raised.

产热和活化能对多滑移 MHD 麦克斯韦流体的影响

这项研究深入研究了麦克斯韦流体流动的复杂流体动力学,以及多孔水平板上的热质传递特征。研究范围包括磁流体动力学、发热、辐射、化学反应和活化能的影响。此外,该研究还整合了流体和固体表面之间界面处的温度、速度和浓度梯度的滑移条件。用上述参数建立控制方程后,通过相似旋转将偏微分方程转化为普通方程。 MATLAB 中 bvp4c 求解器的结果为了解各种物理参数如何相互作用以及如何影响流动动力学和热质传递特性提供了重要见解。本研究的主要目的和目标是通过将固定值视为 Pr,综合比较无滑移和滑移条件下不同参数生成的图。本研究的主要发现表明,随着功率指数的增加,功率指数下降浓度分布。相反,活化能的增加导致该轮廓的升高。这项研究的一个重要启示是,随着活化能参数的升高,观察到浓度分布显着下降。
