摘要
本研究探讨了在多孔介质中存在达西-福克海默效应、索雷特效应和杜富尔效应的情况下,可变导热系数对旋转垂直锥体上的多流体力学流体的影响。非线性微分方程系统被转换为一阶微分方程,并在 Matlab 软件包 Bvp4c 中使用射击技术进行求解。结果表明,导热系数会增加切向速度和温度,降低法向速度。杜富尔参数会增加切向速度,降低法向速度。辐射参数 R 会增加切向速度和温度。
Effects of Variable Thermal Conductivity on MHD Fluid Flow on Rotating Vertical Cone in the Presence of Darcy Forchheimer, Soret and Dufour Effects through a Porous Medium
This research investigated the effects of Variable Thermal Conductivity on MHD fluid on a Rotating Vertical Cone in the Presence of Darcy Forchheimer, Soret and Dufour effects through a porous medium. The system of nonlinear differential equations were transformed into first order differential equations and solved using shooting technique in Matlab package Bvp4c.Furthermore, the effects of various parameters over the main physical quantities are shown graphically and also extensively discussed. The result shows that Thermal conductivity increases Tangential Velocity, Temperature and decreases Normal Velocity. Dufour increases Tangential Velocity and decreases Normal Velocity. Radiation parameter R enhances Tangential Velocity and Temperature.
