SINOPSIS

Invoking a suitable approximation method, we have analyzed the flow pattern generated due to the interaction of a standing sound wave in the presence of a transverse magnetic field with a fluid which is slowly discharged from the porous wall. Also, the superposition of a secondary flow field in the presence of a magnetic field and the velocity of discharge, ν0, affects the flow pattern. This problem is tackled by invoking the method of successive approximations with respect to the small quantity U0, the amplitude of velocity fluctuations in the sound wave. Notably, the impact of porous wall and magnetic field results in damping. It has been shown graphically that there will be no oscillations in the velocity due to the presence of the magnetic field.
