PERISTALTIC FLOW OF SECOND-GRADE DUSTY FLUID THROUGH A POROUS MEDIUM IN AN ASYMMETRIC CHANNEL

In this paper, the effect of porous passage on dusty second-grade fluid with the slip parameter in an asymmetric channel has been studied. The situation is demonstrated mathematically using nonlinear coupled equations. An analytical solution of the problem is gained by applying a regular perturbation method. The stream functions for both fluid and solid particles and the pressure gradient are calculated and illustrated graphically. It is observed that the bolus expands in the upper half of the channel for both fluid and dust particles as k increases, and increasing k has opposite effect in the lower part of the passage.
