Abstract

This article scrutinizes the impact of thermal radiation and applied magnetic field on Jeffrey fluid with peristalsis. The effects of Joule heating and viscous dissipation are retained. Convective conditions are imposed for the heat and mass transfer analysis. Lubrication approach is considered for the analysis. Expressions for pressure gradient, stream function, temperature, concentration and heat transfer coefficient are developed and physically interpreted through illustrations. From obtained outcomes it is revealed that temperature enhances for higher estimation of Brinkman and Hartmann numbers while it decays for larger Biot number. Furthermore, the concentration decreases for varying Schmidth number. Heat transfer coefficient has an oscillatory behavior for larger estimation of radiation parameter.
