Exploring thermal and solutal features in stagnation point flow of Casson fluid over an exponentially radiative and reactive vertical sheet

The stagnation point flow of hydromagnetic Casson liquid flow under an exponentially moving vertical sheet has attracted much attention due to its wide applications. The current investigation considers an incompressible hydromagnetic reacting Casson stagnation point flow in a moving exponential plate and permeable medium. The reduced ordinary quasi-linear derivative equations via similarity transformation and the derivative model are solved computationally through fourth-order Runge–Kutta with a shooting scheme and implemented in MAPLE. The momentum, thermic, and mass transfer profiles and the effect of varying flow terms on the flow variables are determined, and the results are illustrated graphically. The investigations revealed that higher Grashof and Casson term augments velocity. The skin friction characteristic decreases when the flow parameter porosity and Grashof number estimations are dropped. Better heat transfer performance is recorded for thermal solid radiation. The mass transfer characteristics factor decreases when the flow parameter estimations are raised. The proposed model convergence is achieved and presented in the table. The old results agreed with the present; this shows that the numerical method is suitable for solving the model.
