Abstract

Abstract: The aim of present investigation is to model and analyze the magnetohydrodynamic (MHD) peristaltic transport of Prandtl fluid in a channel with flexible walls. The whole system consisting of fluid and channel are in a rotating frame of reference with uniform angular velocity. Viscous dissipation in thermal equation is not ignored. The channel boundaries satisfy the convective conditions in terms of temperature. The arising complicated problems are reduced in solvable form using large wavelength and small Reynolds number assumptions. Numerical solution for axial and secondary velocities, temperature and heat transfer coefficient are presented. Main emphasis is given to the outcome of rotation and material parameters of Prandtl fluid on the physical quantities of interest. Highlights: Peristalsis in a rotating channel is addressed. Prandtl fluid with magnetic field effect is examined. Impact of viscous dissipation with convective boundary conditions is also present. Problem is formulated with compliant channel walls. Closed form solutions have been presented.
