Similarity Solutions of MHD Mixed Convection Flow with Variable Reactive Index, Magnetic Field, and Velocity Slip Near a Moving Horizontal Plate: A Group Theory Approach

Abstract EN

The mixed convection of Newtonian fluid flow along a moving horizontal plate with higher-order chemical reaction, variable concentration reactant, and variable wall temperature and concentration is considered.

Velocity slip and the thermal convective boundary conditions are applied at the plate surface.

The governing partial differential equations are transformed into similarity equations via dimensionless similarity transformations developed by one-parameter continuous group method.

The numerical solutions of the transformed ordinary differential equations are constructed for velocity, temperature and concentration functions, the skin friction factor, the rate of heat, and the rate of mass transfer using an implicit finite difference numerical technique.

The investigated parameters are buoyancy parameters λ1, λ2, chemical reaction parameter K, suction/injection parameter fw, velocity slip parameter a convective heat transfer parameter γ, magnetic parameter M, Prandtl number Pr and Schmidt number, Sc.

Comparison with results from the open literature shows a very good agreement.
