Abstract The persistence of the current article is to discuss the iron nanoparticles' shape in flows due to highly oscillating magnetic field over a stretchable rotating disk. For ferrofluid, water is considered as base fluid with suspension of iron nanoparticles having sphere, oblate ellipsoid and prolate ellipsoid shapes with different sizes. The impact of the nanoparticles' shape on velocity and temperature profiles, convective heat transfer coefficient, radial and transverse shear stress is deliberated through graphs and tables. The presence of highly oscillating magnetic field forces the particles to rotate faster than the fluid and, as a result, the total viscosity is certainly reduced. The governing equations, which are firstly modeled and thereafter converted into nonlinear ordinary differential equations in dimensionless form using similarity approach, are analytically solved using the Mathematica package BVPh 2.0 which is based on the homotopy analysis method (HAM).

铁纳米粒子形状对高振荡磁场下可拉伸旋转盘上铁磁流体对流流动的影响

摘要 本文的持续性是讨论铁纳米粒子在可拉伸旋转盘上的强振荡磁场在流动中的形状。对于铁磁流体，水被认为是具有不同尺寸的球形、扁椭圆体和长椭圆体形状的铁纳米颗粒的悬浮液的基础流体。纳米颗粒的形状对速度和温度分布、对流热传递系数、径向和横向剪切应力的影响通过图表进行了讨论。高振荡磁场的存在迫使粒子比流体旋转得更快，因此，总粘度肯定会降低。控制方程，
