Abstract
The results were obtained graphically with coding in Mathematica. Computational work was carried out for sufficient ranges of parameters of the study namely Schmidt, Radiation, Prandtl, Heat function , Microrotational Modified Grashofs number Electroconductivity, Magnetic field term, Chemical potential. The effects of these parameters on the physical quantities like the Nusselt, Skin-friction coefficient Velocity, Angular velocity, Energy and Concentration profile are all presented graphically. We noticed that the energy profile decreases when the Prandtl number is increased for heat source but increases for the heat sink. The Schmidt and the chemical potential behave the same way for both concentration profile and Sherwood profile. For the electroconductivity and the magnetic field term when they have increased the velocity, and the skin friction profile decreases this shows that they both acts as an opposition to the flow of the fluid.
