摘要

考虑分数阶麦克斯韦流体的磁流体动力学(MHD)流过指数加速垂直板。此外，问题中还使用了其他因素，如产热和化学反应。采用卡普托分数阶导数法求解流动模型。首先对控制方程进行无因次化处理，然后用拉普拉斯变换求解。通过大量的图讨论了扩散热、分数参数、磁场、化学反应、普朗特数和麦克斯韦参数等不同参数的影响。从图中可以看出，流体运动随着施密特数和化学反应的增大而减小，速度场随着扩散热和产热的减小而减小。

EFFECT OF DIFFUSION-THERMO ON MHD FLOW OF MAXWELL FLUID WITH HEAT AND MASS TRANSFER

A magnetohydrodynamics (MHD) flow of fractional Maxwell fluid past an exponentially accelerated vertical plate is considered. In addition, other factors such as heat generation and chemical reaction are used in the problem. The flow model is solved using Caputo fractional derivative. Initially, the governing equations are made non-dimensional and then solved by Laplace transform. The influence of different parameters like diffusion thermo, fractional parameter, Magnetic field, chemical reaction, Prandtl number and Maxwell parameter are discussed through numerous graphs. From figures, it is observed that fluid motion decreases with increasing values of Schmidt number and chemical reaction, whereas velocity field decreases with decreasing values of diffusion thermo and heat generation.
