Abstract
An investigation of inclined magnetic field on unsteady natural convection heat and mass transfer flow past an oscillating slanted plate embedded in a homogeneous permeable medium with destructive chemical reaction and thermal radiation under time-varying fluid temperature and species concentration is carried out. Exact solutions to the equations governing the flow are obtained in closed form utilizing Laplace transform technique. The values of fluid velocity, fluid temperature, and species concentration are presented graphically, while skin friction, mass, and heat transfer rates are recorded in tabular form for different values of important flow entities. We note that an increase in the angle of the applied magnetic field or the inclination of the plate reduces fluid velocity while it enhances local skin friction. However, an increase of phase angle diminishes both the fluid velocity and its gradient at the wall of the plate.
