Computational modelling of chemically reactive and radiative flow of Casson-Carreau nanofluids over an inclined cylindrical surface with bended Lorentz force presence in porous medium

Abstract

The main objective of this study is to investigate magnetohydrodynamics (MHD) boundary layer heat and mass transfer analysis for Casson-Carrreau nanofluids flowing over an inclined cylindrical surface with bended Lorentz force, presence in porous medium. The effects of thermal radiation, higher order chemical reaction, heat generation, Soret and Dufour effects are also considered in multiphase fluid flow. The established partial differential governing equations are transformed into dimensionless momentum, energy and concentric equations and are solved numerically by using explicit finite difference method (EFDM) with employing Compact visual FORTRAN 6.6a programming algorithm. In order to test the accuracy of the system, the stability and convergence analysis are carried out by applying the initial and boundary conditions. A tabular comparison is also shown to validate the numerical modelling and an excellent agreement is found. The obtained results are discussed for several values of physical parameters viz. Prandtl number, magnetic parameter, Casson fluid parameter, Weissenberg number, thermal Grashof number, mass Grashof number, Biot number, phase angle parameter, Darcy number, heat source parameter, chemical reaction, order of chemical reaction, radiation, Soret and Dufour number, Eckert number, Lewis number, Brownian motion and thermophoresis number on the velocity, temperature, concentration, skin friction, Nusselt number. Finally, it is concluded that the heat and mass transform accomplishment of Casson fluid is relatively lower than that of Carreau fluid.
