Dynamics of Walters’ B fluid due to periodic wave in a convectively heated channel with internal heat generation

Abstract

Peristaltic transport is very useful in human physiological system such as the spermatic movement, circulation of blood, urine transportation, etc. The aim is to study the transport of MHD Walters’ B fluid through a curved channel with heat source/sink, chemical reaction and viscous dissipation with compliant and convectively heated walls. Resulting problem is executed via numerical approach. Graphical illustrations for impact of emerging physical parameters on velocity, temperature, rate of heat transfer and concentration are prepared and examined physically. The effects of wall’s elasticity, fluid and curvature parameters show an increase in velocity, whilst for Hartmann number and damping effect the reverse response of velocity is noticed. Brinkmann and Biot numbers tend to increase the temperature profile and concentration reduces for increase in values of curvature parameter.
