MODELLING OF MHD VISCOELASTIC FLUID FLOW IN A CIRCULAR STRETCHING SHEET WITH SORET, DUFOUR AND ARRHENIUS ACTIVATION ENERGY

Abstract

Analysis of steady, axisymmetric, hydromagnetic, viscoelastic fluid flow due to a circular sheet stretching radially has been made in presence of nonlinear thermal radiation, heat source, Arrhenius activation energy, Soret and Dufour effects. To study the viscoelastic fluid, Maxwell fluid model has been adopted. Governing simultaneous partial differential equations are reduced to ordinary differential equations by using similarity transformations. The ordinary differential equations are solved by using bvp4c method. The obtained results are shown graphically to illustrate the impact of pertinent physical parameters on velocity, temperature, concentration, skin friction, heat transfer and mass transfer.
