This research investigates the impact of second-order slip conditions, Stefan flow, and convective boundary constraints on stagnation-point flow couple stress nanofluids over a solid sphere. The nanofluid density is expressed as nonlinear function temperature, while diffusion-thermo effect, chemical reaction, thermal radiation are incorporated through linear models. governing equations transformed using appropriate non-similar transformations solved numerically via finite difference method (FDM). Key physical parameters, including heat transfer rate, analyzed in relation to Dufour number, velocity, parameters an artificial neural network (ANN) framework. Furthermore, response surface methodology (RSM) employed optimize skin friction, transfer, mass by considering influence radiation, slip, reaction rate. Results indicate that velocity enhances behavior reducing temperature concentration distributions. Additionally, increase number leads higher profiles, ultimately lowering overall ANN-based predictive model exhibits high accuracy with minimal errors, offering robust tool for analyzing optimizing transport characteristics nanofluids.

ABSTRACT Researchers have significantly explored the fluid motion over rotating surfaces for their significant uses in many technical and manufacturing processes, including centrifugal compressors, gas steam turbines, viscometers, pumps, fans, spin‐coating, computer storage systems. A low‐oscillating magnetic field plays a crucial role heat transport efficiency, nanoparticle manipulation, enhancement of stability rheology. In view this, present study explores consequence on three‐dimensional unsteady stream nanofluid past slowly revolving disk with quadratic thermal radiation, variable conductivity, suction, activation energy. The generalized Fouriers Ficks law is also considered to analyze mass transport. governing partial differential equations are transformed into dimensionless ordinary suitable similarity variables. finite difference technique utilized solve resulting (ODEs) numerically. impact various factors concentration, velocity, temperature profiles shown visually. For unsteadiness parameter, skin friction increases by approximately 5.29%. As suction parameter values rise, velocity decreases. profile rise conductivity parameter's value. radiation intensifies profile. concentration reduces as relaxation time increases.
