Abstract

The current study is dedicated to presenting the Casson nanofluid over a stretching surface with activation energy. In order to make the problem more realistic, we employed magnetic field and slip effects on fluid flow. The governing partial differential equations (PDEs) were converted to ordinary differential equations (ODEs) by similarity variables and then solved numerically. The MATLAB built-in command ‘bvp4c’ is utilized to solve the system of ODEs. Central composite factorial design based response surface methodology (RSM) is also employed for optimization. For this, quadratic regression is used for data analysis. The results are concluded by means of tables and pictorial representations. The present study discloses that the temperature profile increases with enhancement in Ha, N_r, N_b, and N_t and it shows opposite behavior for λ. The included parameters show same trend for heat transfer rate (Nu_x). It is also concluded that δ should be maximum for any value of N_b and N_t to maximize the heat transfer rate.
