In this mathematical study, the effect of buoyancy parameters along with radiation on magneto-hydrodynamic (MHD) micro-polar nano-fluid flow over a stretching/shrinking sheet is taken into consideration. Suitable similarity variables are used to convert the governing non-linear partial differential equations into a system of coupled non-linear ordinary differential equations which are then numerically solved by R.K method with shooting scheme. The influence of pertinent parameters on the velocity profile, temperature profile, micro-rotation profile, and concentration profile is investigated. It is founded that the velocity profile is decreased with the increment in the values of M and the opposite behavior is noticed for micro-rotation, thermal, and concentration profiles. It is also founded that an increase in the values of buoyancy parameters causes an increase in velocity profile while micro-rotation, thermal, and concentration profiles are decreased. The results are exposed and discussed through tables and graphs.
