Successive over relaxation (SOR) methodology for convective triply diffusive magnetic flowing via a porous horizontal plate with diverse irreversibilities
Entropy generation and triple diffusive convection is not explored yet taking the combined effects of suction and magnetohydrodynamic in a flow through porous medium. Irreversibility in mass diffusivity due to magnetic field has substantial effects on mass and heat transport rate. A novel model obey...

| description | Entropy generation and triple diffusive convection is not explored yet taking the combined effects of suction and magnetohydrodynamic in a flow through porous medium. Irreversibility in mass diffusivity due to magnetic field has substantial effects on mass and heat transport rate. A novel model obeying Darcy law and Boussinesq approximation is developed for the entropy generation analysis under the influence of coupling effects of concentrations of two heterogeneous salts in the flow of a Newtonian fluid. Magnetic Bejan number and mass Bejan number have been defined for the estimation of novel irreversibilities due to salts’ concentrations and magnetic retardation. Governing equations are transformed by employing similarity variables; the dimensionless system thus obtained is discretized by the finite differences and, then simulated numerically via Successive over Relaxation (SOR) methodology. It’s worth noting that suction at the surface along with magnetic force and porosity tends to decrease local as well as surface entropy generation rates and also the novel magnetic Bejan number considerably. Furthermore, entropy generation rate in triple diffusion is higher than double diffusion. |
