Investigation of peristaltic flow of Williamson nanofluid in a curved channel with compliant walls

In the present paper, we have examined the peristaltic flow of Williamson nanofluid in a curved channel comprising compliant walls. The governing equations of a Williamson fluid model with nanoparticles for curved channel are derived, including the effects of curvature and heat dissipation. The highly nonlinear, partial differential equations are simplified by using the wave frame transformation, long wave length and low Reynolds number assumptions. The reduced, nonlinear, coupled differential equations are solved analytically with the help of the homotopy perturbation method. The physical features of pertinent parameters have been discussed by plotting the graphs of velocity, temperature, concentration profile and stream functions.
