摘要

近年来,粘性流体的磁流体动力学研究由于其实际意义和在天体物理和地球物理现象中的许多应用而变得越来越重要。本文利用径向基函数求解流体在磁场作用下通过两个平行平板的分数阶方程。磁流体力学耦合应力流体在两个平行板之间流动,底板静止,顶板以恒定速度运动。将径向基函数方法与数值方法(四阶Range-Kutta)进行了比较,以验证其有效性。结果表明,这两种技术之间的差异是相当微不足道的,表明该方法是非常可靠的。说明了磁场参数和雷诺数对垂直于流体流动方向的速度分布的影响。最后,比较了不同条件α、雷诺数和位置(y)下的速度参数,其中最大值出现在α = 0.4时。最大速度值出现在α=0.4和Re=1000时,α=0.8时曲线的凹凸度较小。

Mathematical modeling of fractional derivatives for magnetohydrodynamic fluid flow between two parallel plates by the radial basis function method

Investigations into the magnetohydrodynamics of viscous fluids have become more important in recent years, owing to their practical significance and numerous applications in astro-physical and geo-physical phenomena. In this paper, the radial base function was utilized to answer fractional equation associated with fluid flow passing through two parallel flat plates with a magnetic field. The magnetohydrodynamics coupled stress fluid flows between two parallel plates, with the bottom plate being stationary and the top plate moving at a persistent velocity. We compared the radial basis function approach to the numerical method (fourth-order Range-Kutta) in order to verify its validity. The findings demonstrated that the discrepancy between these two techniques is quite negligible, indicating that this method is very reliable. The impact of the magnetic field parameter and Reynolds number on the velocity distribution perpendicular to the fluid flow direction is illustrated. Eventually, the velocity parameter is compared for diverse conditions α, Reynolds and position (y), the maximum of which occurs at α = 0.4. Also, the maximum velocity values occur in α=0.4 and Re=1000 and the concavity of the graph is less for α=0.8.
