Computational study: sinusoidal mass transfer into unsteady magnetohydrodynamic flow over a yawed cylinder

The investigation of how sinusoidal mass transfer, variable viscosity, and Prandtl number affect unsteady magnetohydrodynamic flow over a yawed cylinder is the core intention of this work. The coupled non-linear partial differential equations of the flow field are linearized via quasilinearization, and an implicit finite difference scheme is employed to yield non-similar solutions. In both steady and unsteady cases, an enhancement in the magnetohydrodynamic parameter or a reduction in yaw angle boosts the skin friction coefficient in the axial direction and the heat transfer coefficient. The aforesaid effects, however, are reversed for skin friction coefficient in the spanwise direction. The skin friction and heat transfer coefficients grow as the time parameter rises, regardless of the magnetic field or yaw angle. When a sinusoidal slot suction is used in the unsteady case, zero skin friction in the axial direction is averted.
