ABSTRAKT

The flow of micropolar fluid inside a circular cylinder that is subjected to longitudinal and torsional oscillations with different frequencies is investigated. Analytical expressions for the velocity components and microrotation components are obtained in terms of modified Bessel's functions. The drag force acting on the wall of the cylinder is derived. It is observed that as the micropolarity of the fluid increases, drag decreases.
