Abstract

Numerical investigations are performed to analyze heat and mass transfer in MHD (magnetohydro-dynamic) nanofluid flow over a shrinking sheet in the presence of thermal radiation and chemical  reaction with Soret effect. The transport equations involve the effect of Brownian motion, Thermophoresis, viscous dissipation, suction/injection, partial slip velocity and thermal  slip. Using self suitable transformations, the governing equations are reduced to ordinary  differential equations, further these equations are solved numerically using Runge-Kutta fourth  order method with shooting technique. This study reveals that the governing parameters, namely,  magnetic field parameter, thermal radiation parameter, chemical reaction parameter, velocity slip  parameter etc., have major effects on velocity, temperature, concentration, skin friction  coefficient and Nusselt number. The study admits that concentration rises with an increase in the  Soret number. Numerical results are discussed with the assistance of graphs. The present problem  has multiple applications in polymer, chemical and metallurgical industries such as formation of  metallic and glass sheets.
