Numerical investigation of tangent hyperbolic stagnation point flow over a stretching cylinder subject to solutal and thermal stratified conditions

Tangent hyperbolic fluid (THF) is frequently used in mathematical modeling and simulations of fluid dynamics, particularly in multiple industrial applications, such as the study of polymers, biological fluids, colloids, material science, chemical engineering, biological mechanics, and heat transmission. The stagnation point flow of MHD (magnetohydrodynamics) THF across a stretching cylinder is studied in the current investigation. The flow has been observed under the consequences of chemical reactions, heat radiation, heat generation/absorption, activation energy, and Joule heating. The flow is also subject to solutal and thermal stratified conditions and porous medium. The modeled equations are changed into dimensionless form of ODEs, which are numerically solved through the parametric continuation method (PCM). It can be concluded from the results that the flow rate enriches with the effect of buoyancy forces and mixed convection parameters, whereas it declines with the impact of local Weissenberg number and porosity parameters. The thermal and concentration distribution rate reduces with the variation of stratification parameters.
