摘要

本文对含新型(Ag + MgO)-水混合纳米流体(HNF)的非定常磁流体动力学(MHD) Couette流动进行了数值研究。将银纳米粒子(Ag)和氧化镁纳米粒子(MgO)补充到基础流体水中。顶壁保持均匀运动，而槽底壁固定并可拉伸。垂直于下板施加外磁场。采用有限差分法对非线性偏微分方程进行求解。比较了混合纳米流体和纳米流体(NF)对重要参数的影响，并给出了图形。结果表明，(Ag + MgO)-水HNF对Couette通道内的流速和温度有显著影响。

Effectiveness of silver-magnesium oxide-water hybrid nanofluid in Couette channel

The present article numerically investigates the unsteady magnetohydrodynamic (MHD) Couette flow containing novel (Ag + MgO)-water hybrid nanofluid (HNF). The nanoparticles of silver (Ag) and magnesium oxide (MgO) are supplemented to base fluid water. The top wall is kept in uniform motion while the bottom wall of channel set stationary and stretchable. An external magnetic field is applied perpendicular to lower plate. The governed nonlinear partial differential equations (PDE) are solved employing finite difference method (FDM). The effects of hybrid nanofluid and nanofluid (NF) are compared for the significant parameters and presented graphically. The results illustrate that (Ag + MgO)-water HNF exhibits significant influence over Ag-water NF on velocity and temperature in the Couette channel.
