Description
Summary:This article addresses MHD Jeffrey fluid flow between two stretchable rotating disks. Momentum equation with magnetic field is presented. Energy equation is constructed in presence of heat source/sink and nonlinear radiation. Thermal stratification and homogeneous-heterogeneous reactions are accounted. The related systems have been solved for convergent solutions. Velocity, temperature, concentration, skin friction coefficient and Nusselt number are analyzed. The velocities (radial, axial, tangential) are increasing functions of Deborah number. Decline in axial velocity is noticed at lower disk for larger ratio of relaxation to retardation times constant. Thermal field is enhanced for temperature ratio parameter. Concentration has opposite behavior for larger homogeneous parameter and Schmidt number. Surface drag force decays for larger ratio of relaxation to retardation times at both disks. Heat transfer rate enhances for temperature ratio parameter.
