Abstract This study analyzes the effects of thermal radiation in a rotating frame with peristaltic motion couple stress nanofluids. The channel rotates at constant angular speed around z ‐axis and is filled fluid. Heat mass transfer effects, including thermo‐diffusion (Dufour) thermal‐diffusion (Soret) are considered along convective boundary conditions viscous dissipation. aims to understand behavior nanofluids under rotation, influenced by thermophoresis Brownian motion. governing nonlinear equations transformed into dimensionless form assumptions long wavelength low Reynolds number solved numerically using MATHEMATICA NDSolve function. results reveal that rotation enhances primary velocity while reducing secondary velocity. Soret Dufour significantly influence concentration distribution, exhibit opposite impacts on temperature concentration. analysis isotherms contours highlights variations nanoparticle distribution. These findings provide valuable insights interplay peristalsis, nanofluid transport, applications biomedical engineering, microfluidic systems, industrial heat exchangers.

This article investigates the flow and heat transfer of a nanofluid liquid film containing carbon nanotube nanoparticles over stretching surface under influence an aligned magnetic field in Darcy‐Forchheimer absorbent medium. The study examines two aqueous‐based combinations: one with single‐wall nanotubes (SWCNTs) other multi‐WCNTs (MWCNTs). choice these is owing to their amazing characteristics including feather‐weight, remarkable thermal electrical conductivities, chemical mechanical steadiness. These flows are influenced by variable nonuniform source/sink effects radiation. Furthermore, analysis incorporates distinct homogeneous‐heterogeneous (h‐h) reactions. novel unsupervised Morlet wavelet neural networks (MW‐NNs), combined heuristic algorithm, used solve nonlinear ordinary differential equations (ODEs). MW function transforms ODEs into artificial NNs‐based fitness then particle swarm optimization (PSO) for optimal values. weights MW‐NNs optimized using PSO within range −10 10. To evaluate convergence this approach, fifty independent runs were performed compute statistical results presented through illustrations tabulated estimates. It witnessed that fluid velocity shows conflicting trends thickness parameters. also examined temperature enhanced radiation

The heterogeneous fluid model is expressed for the nanofluid flow to study significance of Fourier’s and Fick’s laws. magnetohydrodynamics couple-stress bioconvective considered across an extending surface with effect exponential heat source/sink stratified boundary conditions. solid nanoparticulates concentrations motile microorganisms are added nonlinear system differential equations conveying non-Newtonian nanoliquid model. Moreover, combined flux thermal radiation also evaluated. similarity transformations employed transfigure partial into lowest order ordinary equations. Artificial Neural Network Levenberg Marquardt Back-propagation optimization algorithm solve these To authenticate outcomes, dataset formed using MATLAB package “bvp4c”. created diverse circumstances factors, as well validation testing Network. accuracy estimated through numerous statistical tools (histogram, curve fitting, regression measures, performance plots). outcomes presented table figures.
