Purpose The analysis of stagnation point in non-Newtonian fluid is considerable interest among the scientific communities; however, very few studies are reported on double-stratified porous mediums. This paper aims to elucidate electromagnetohydrodynamic hyperbolic tangent nanofluid. Thermal and solutal stratification effects considered stagnant flow medium adds more intricacy novelty findings, which contribute understanding specific structural designs aircraft transport modelling, groundwater contamination bio-energy production. Entropy generation intensification heat transfer. Design/methodology/approach Fifth-order Runge–Kutta–Fehlberg method via shooting technique used solve highly nonlinear ODEs. Numerical understand nature surface drag force, local Nusselt number Sherwood with various parameters incorporated. Findings Key findings reveal that a temperature concentration profile diminishes increasing parameter. Heat transfer rate rises by 17.8% due Prandtl number, whereas mass increases as 108.5% thermophoresis Furthermore, systems entropy reduced 10.77% while power law index parameter Originality/value concept stratified scenarios represents significant advancement, appearing across diverse natural engineering such oceanography, geophysics environmental science. Minimizing total production essential for enhancing efficiency achieving superior outcomes numerous applications.
