Summary
The effects of constant suction or injection of a homogeneous viscous fluid on the oscillatory flow past a porous disk are studied. Due to the oscillatory free stream, a secondary flow with the tangential components of velocity alone is produced. Separate solutions for low and high frequencies of oscillation are obtained. The streamwise and crosswise components of the oscillatory flow are obtained by choosing suitable forms for the low-and high-frequency oscillations. Expressions for the correction to the shearing stress at the surface due to the secondary flow are presented.
