Abstract

This study explored the double-stratified micropolar nanofluid stagnation point flow enclosed by porous medium with activation energy and chemical reaction. The phenomena of hydrodynamic magnetic field acting normal direction to stretching surface also incorporated here. System of governing equations are owned by key parameters and converted into ODEs with help of similarity transformation. Numerical solutions are encountered with the aid of Runge-Kutta-Fehlberg 5th order method, accompanied by shooting technique. Comparison between skin friction coefficient and local couple stress in micropolar constant and porous parameter with well-known research findings is also reported. Numerical formulation and investigation are made on local skin friction, local couple stress, heat and mass transfer rate in various parameters. A pictorial representation of abundant parameterson linear and angular velocity, temperature and concentration field is analyzed. The gradual gain of the micropolar constant enhances the fluid’s velocity and angular velocity profile. Solutal and chemical reaction rate constant are diminish the mass transfer of fluid. This study can be used in many eye-catching applications, such as biomedical engineering, lap-on-a-chip devices, cooling agent in electrical devices, automobiles and oil recovery processes.
