Three-dimensional unsteady squeezing flow with irreversibility

Abstract

This exploration examines unsteady magnetohydrodynamic (MHD) three-dimensional flow of viscous material between rotating plates subject to radiation, Joule heating and chemical reaction. The non-linear partial differential system is re-structured into the ordinary differential expressions by the implication of appropriate transformations. The developed differential equations are computed by homotopy analysis technique. Numerical consequences have been accomplished by various values of emerging parameters. Coefficients of skin friction and heat and mass transfer rates have been scrutinized. Irreversibility analysis is carried out. Influence of various prominent variables on entropy generation is presented. Moreover, the temperature increases for higher Dufour number and concentration distribution reduces against Soret number. Higher squeezing parameter enhances velocity while concentration reduces with an increment in squeezing parameter. Both entropy rate and Bejan number increase against higher diffusion parameter.
