Hybrid ANN–RSM modeling and sensitivity analysis of skin friction in Sisko fluid flow over a porous exponentially stretching sheet

This study investigates the steady, two-dimensional flow of Sisko fluid with a chemical reaction over an exponential sheet, employing suitable similarity variables to transform the governing partial differential equations into ordinary differential equations. The research is carried out in three phases: first, acquisition of the numerical data by the employment of the BVP4C solver; then, Response surface methodology (RSM) analysis serves to analyze the impact of the different parameters on the c
