Abstract

Heat transfer effect on the flow of Herschel Bulkley fluid moving in a non-uniform channel is analyzed. The peristaltic wall is considered to be coated with a porous lining. The pertinent parameter effects are studied graphically for the analytical solutions of temperature profile, rate of temperature, heat transfer coefficient and mechanical efficiency. The temperature profile, heat transfer coefficient and the rate of temperature decrease with increase in the Darcy number. Thickening of the porous wall coating raises the temperature profile and the rate measure of temperature. Mechanical efficiency is more in a convergent channel than in uniform and divergent channels.
