Heat and mass transport characteristics in viscous slip flow over a curved surface and entropy production

ABSTRACT
This study deals with heat and mass transport in viscous slip flow over a curved, permeable sheet stretching linearly in a porous medium. Various factors influencing heat and mass transport, such as non-uniform heat generation/absorption, thermal radiation, chemical reaction, and viscous dissipation, are invoked in the study. Under appropriate similarity transformation relations, the governing nonlinear PDEs are turned into ODEs in non-dimensional form, and then tackled numerically utilizing MATLbased bvp4c technique. The impacts of pertinent parameters are exhibited graphically on various relevant fields (velocity field, temperature field, concentration field) and discussed. Second law analysis is also presented in terms of entropy generation. Moreover, values of skin friction coefficient, Nusselt number, and Sherwood number are computed and presented in tabular form. For validity of the results obtained, the skin friction coefficient values are compared with previously published data and found to be in good agreement.
