Abstract
The current study discusses the mixed convection boundary layer around an isothermal solid sphere utilizing numerical simulation; two fluid types of hybrid and mono micropolar nanofluids with constant wall temperature in an MHD field are examined. To improve a base fluid's thermophysical, optical, rheological, and morphological qualities, two different types of nanoparticles Copper oxide CuO and Graphite oxide (GO) are combined to create hybrid nanofluids. The sensitivity analysis was made to unveil the impacts of the mixed convection factor, the field strength and the micro-rotation factor. The results reveal that the improving effect of using NF by the induced micro-rotational effect is more prominent at lower angles and diminished at higher angles. Another point that could be obtained is that the thermal boundary layer thickness is directly proportional to the magnetic parameter; by increasing the M value from 0.5 to 2, the thermal boundary layer thickness increases from 1.4 to 1.8. Also, using hybrid instead of mono NF has nearly no effect on altering the angular velocity at y > 4; for other ones (y < 4), the difference is<15 %.
