Abstract : This paper investigates the provoked flow pattern due to an impulsive motion of porous wavy wall with no slip suction velocity under the influence of magnetic field. It is assumed that the amplitude of the wall is much smaller than the developed boundary-layer thickness. This engendered flow pattern has two significant flow regimes: Regime-I near to the wall boundary where flow is affected due to waviness and viscosity and Regime-II is adjacent to the boundary-layer region, i.e., in the core region. Flows in these regimes are governed by boundary-layer equations, and their solution is determined by considering the expansion in terms of smallness of the amplitude oscillations. Results obtained are depicted graphically. It is shown that the magnetic field and suction parameter tend to pull down the effect of Reynolds stress.
