Navier slip and suction/injection effects on oscillatory flow of nanofluid with fluid-particle interaction in a channel

Abstract

In this paper, the slip and porosity effects on the channel walls are studied for the oscillatory flow of heat-absorbing/generating dusty nanofluid flowing through a porous medium. The channel is vertical and exposed to the transverse magnetic field and thermal radiation. The base fluid is water with silver as nanoparticles. The basic equations of the flow problem, which appeared to be dimensional, are remodelled in the dimension-less form with the help of non-dimensional variables. The obtained equations are solved analytically using the variable separable method. The graphs are presented to show the impact of these parameters on the flow fields, skin friction, heat transmission rate and discussed in detail. Results reveal that the flow velocities of fluid and particles for suction are greater than in the case of injection. The fluid velocity upsurges with the improved values of the velocity slip parameter.
