A computational study on the MHD Casson fluid flow with thermal radiation and variable physical properties under the influence of Soret and Dufour effects

Abstract

AbstractThis research study discusses the flow of a magnetohydrodynamic Casson fluid under the influence of Soret, Dufour, and thermal radiation. Nonlinear partial differential equation (PDE) of governing equations is transformed into a dimensionless version of the modified PDEs presented in terms of dimensionless parameters. The solution of coupled PDEs is obtained by the finite difference method with a combination of the quasilinearization technique. The effects of various dimensionless parameters are shown graphically, such as buoyancy force (), concentration buoyancy force , Casson parameter (), magnetic parameter (), thermal radiation (), Darcy parameter (), Forchheimer (fr), Dufour (), Soret (Sor), Brownian motion (), thermopohersis (), and Lewis number (). Prevention of heat transfer in the industrial system is critical, the velocity behavior (), thermal variation (), and concentration profile () are more prominent in the roles of coal, gas, and solar thermal collectors.
