Abstract
Exact solution of an incompressible fluid of second-order type by causing forced oscillationsin the liquid of finite depth bounded by a porous bottom has been obtained. The results presentedare in terms of nondimensional elastico-viscosity parameter () which depends on the non-Newtonian coefficient and the frequency of excitation () of the external disturbance whileconsidering the porosity (K) of the medium. The flow parameters are found to be identical withthat of Newtonian case as and K. It is seen that the effect of and the porosityof the bounding surface has significant effect on the velocity parameter. Further, the nature ofthe paths of the fluid particles have also been studied with reference to and the porosity ofthe bounding surface.
