MHD PERISTALTIC ROTATING FLOW OF A COUPLE STRESS FLUID THROUGH A POROUS MEDIUM WITHWALL AND SLIP EFFECTS

We have discussed the systematic solution of time-dependent mean velocity on MHD peristaltic rotating flow of an electrically conducting couple stress fluid in a uniform elastic porous channel. The consequence of slip condition has been studied. The precise model is formulated assuming a small Reynolds number and long-wavelength approximations. Various aspects such as magnetic parameter, Darcy number, slip parameter, and couple stress parameter are discussed through graphs under the existence and nonexistence of both stiffness and viscous damping forces. It is noticed that the time-dependent mean velocity decreases with increase in the magnetic parameter in the presence of elastic parameters and flow reversal occurs at the center line of the channel. It reduces with growth in nonzero elastic parameters.
