Unsteady boundary layer magnetohydrodynamics in micropolar fluid past a sphere

We consider heat transfer unsteady boundary layer magnetohydrodynamics in micropolar fluid past a sphere. Dimensional governing equations formed from the physical problem by using the theory of the boundary layer. The dimensional governing equations consist of the continuity equation, momentum equation and energy equation. The dimensional governing equations are further converted into non-dimensional equations by introducing non-dimensional variables. The non-dimensional equations are further transformed into similarity equations and then solved numerically using the Keller-Box method. We obtain that the velocity profiles increase when both the values of magnetic variable, M, and micropolar parameter, K, increase. However, when we increase both these values, we obtain that the value of microrotation decreases.
