The present analysis deals with the three-dimensional radiative, convective hybrid nanofluid flow over a rotating and stretching inclined disk under the action of the applied magnetic field, Joule's heating, and viscous dissipation effects. The mathematical model considers nanoparticles graphene oxide (GO) and molybdenum disulfide (MoS2$_2$) suspended in water as the base fluid within a Darcy medium. The cylindrical coordinate system is used to express continuity, momentum, and energy partial differential equations, out of which momentum and energy partial differential equations are transformed into ordinary differential equations using a suitable transformation method under the boundary-layer approximation. The transformed equations are further solved using the spectral quasi-linearization method. Graphical and numerical data are presented to investigate the behavior of velocity and temperature under various parameters and shape factors. The nature of fluid flow at the boundary wall is determined by tables of skin friction and the Nusselt number. Statistical analysis of the parameters for axial and tangential skin friction and the Nusselt number is performed using the quadratic regression model.

具有耗散传热的斜盘上多孔介质中非稳态磁流体混合纳米流体流动的数值和统计分析

目前的分析涉及在外加磁场、焦耳加热和粘性耗散效应的作用下,三维辐射、对流混合纳米流体在旋转和拉伸倾斜圆盘上流动。数学模型考虑纳米颗粒氧化石墨烯 (GO) 和二硫化钼 (MoS2)2$_2$)悬浮在水中作为达西介质内的基液。柱坐标系用于表达连续性、动量和能量偏微分方程,在边界层近似下利用适当的变换方法将动量和能量偏微分方程转化为常微分方程。使用谱准线性化方法进一步求解变换方程。提供图形和数值数据来研究各种参数和形状因素下的速度和温度行为。边界壁处流体流动的性质由表面摩擦力表和努塞尔数确定。使用二次回归模型对轴向和切向表面摩擦参数以及努塞尔数进行统计分析。
