本研究检查了磁化普朗特流体模型的旋转锥体中的流动。推导了考虑霍尔效应和离子滑移效应的普朗特模型动量方程，并考虑了焦耳热和粘性耗散效应的热传输现象。纳米流体混合物的经验关系考虑了 Hamilton Crosser 和 Yamada Ota 的模型。具有热传输的 Prandtl 流体模型的流动表示形式是在边界层近似下以偏微分方程 (PDE) 的形式进行建模的。通过适当的标度群变换，导出的偏微分方程组已转换为耦合非线性常微分方程组 (ODE)，并且这些转换后的非线性常微分方程组已通过有限元方案 (FES) 进行数值处理。不同新兴参数的影响已以图形方式显示，并详细解释了观察到的现象背后的物理原理。 FES的收敛是通过进行网格独立测量来建立的。根据所进行的研究，记录了由于霍尔和离子滑流电流而出现的参数提高了流体速度，但记录了温度曲线的相反行为。
Flow in a rotating cone for magnetized Prandtl fluid model is inspected in this investigation. The momentum equation of Prandtl model is derived under the consideration of Hall and ion slip effects and heat transport phenomenon is considered with Joule heating and viscous dissipation effects. The model of Hamilton Crosser and Yamada Ota are considered for the empirical relations of nanofluid mixture. The flow presenting expression of Prandtl fluid model with thermal transport is modeled under boundary layer approximation in the form of partial differential equations (PDEs). The derived PDEs have been converted into set of coupled nonlinear ordinary differential equations (ODEs) by engaging an appropriate scaling group transformation and these converted nonlinear set of ODEs have been tackled numerically via finite element scheme (FES). Impact of different emerging parameters has been displayed graphically and the physics behind the observed phenomena is explained in detail. The convergence of FES is established by carrying the grid independent survey. From the performed investigation, it is recorded that the parameters appear due to Hall and Ion slip currents enhance the fluid velocity but the inverse behavior is recorded for temperature profile.
