Analysis of Error and Stability of Nanofluid over Horizontal Channel with Heat/Mass Transfer and Nonlinear Thermal Conductivity

The current investigation aims to analyze the nanofluid flow between two infinite rotating horizontal channels. lower plate is porous and stretchable. impact of physical parameters such as Hall current, thermal characteristics, heat source/sink, chemical reaction on velocity, temperature, concentration profiles are discussed through graphs. governing equations transformed ordinary differential using suitable transformations then solved numerically RK4 approach along with shooting technique. For varying values Schmidt number (SN) factor (CRF), profile declines, but decreases for activation energy. It observed that velocity declines increasing suction factor. increases when rotation factors increased. temperature field exhibits a rising behavior thermophoresis factor, Brownian motion, radiation also transfer rate significant at wall Prandtl (PN). numerical solution, error estimation residue calculated stability confirmation mathematical model. novelty present work investigate irregular source over channel. A growing performance revealed by field, increase in motion (BM), (TF), conductivity (TCF), (RF).
