Numerical study of unsteady MHD oblique stagnation point flow with heat transfer over an oscillating flat plate

Abstract

Unsteady stagnation point flow impinging obliquely on an oscillating flat plate in the presence of a uniform applied magnetic field in a fixed frame has been studied. The governing boundary layer equations are transformed into three coupled, dimensionless, nonlinear, partial differential equations. Here the stream function is expressed as Hiemenz and tangential components. The equations are solved numerically by using the well-known implicit finite difference scheme, called the Keller-box method. To ensure the accuracy of obtained results, numerical results are compared with the results available in the literature. It is observed that the obtained solution is in excellent agreement with previous studies. The effects of pertinent parameters involved in the problem, namely, magnetic parameter, Prandtl number, and impinging angle, on flow and heat transfer characteristics are illustrated. It is observed that the magnetic field helps to translate the oblique stagnation point.
