Impact of Couple Stress with Rotation on Walters, B Fluid in Porous Medium

: With the help of a couple stress model and a porous material, this research examines peristaltic flow of Walter's B fluid through an asymmetric channel. For the balance of mass, motion, trapped phenomena, velocity distribution, and pressure gradient, the constitutive equation is modeled. In the flow analysis, a wavelength with a low Remolds number assumption is chosen, and the perturbation method is used to provide an accurate solution. Gained knowledge includes the impact of various parameters on the confined phenomenon's velocity distribution and pressure gradient. The set of numbers presented here is a graphic analysis of these parameters.
