The flow of a magnetite-H2O nanofluid has been considered among two rotating surfaces, assuming porosity in the upper plate. Furthermore, the lower surface is considered to move with variable speed to induce the forced convection. Centripetal as well as Coriolis forces impacting on the rotating fluid are likewise taken into account. Adequate conversions are employed for the transformation of the governing partial-differential equations into a group of non-dimensional ordinary-differential formulas. Numerical solution of the converted expressions is gained by means of the shooting technique. It is theoretically found that the nanofluid has less skin friction and advanced heat transport rate when compared with the base fluid. The effect of rotation causes the drag force to elevate and reduces the heat transport rate. Streamlines are portrayed to reveal the impact of injection/suction.

Fe3O4 纳米粒子通过可拉伸表面的 MHD 旋转流的传热分析

磁铁矿的流动-H 2O 纳米流体已被考虑在两个旋转表面之间,假设上板有孔隙。此外,下表面被认为以可变速度移动以引起强制对流。同样考虑了影响旋转流体的向心力和科里奥利力。充分的转换用于将控制偏微分方程转换为一组无量纲常微分公式。转换后的表达式的数值解是通过拍摄技术获得的。理论上发现,与基础流体相比,纳米流体具有更小的皮肤摩擦和更高的热传输率。旋转的作用导致阻力升高并降低热传输率。
