摘要

The current analysis focuses on the thin film flow of the Carreau nanofluid over an unsteady rotating and inclined disk. The liquid film of the Carreau fluid’s flow field is taken into account within the Darcy–Forchheimer porous space. Thermal radiation and chemical reactions are used to describe the model problem. The control volume finite element method is used to solve the governing partial differential equations, and the homotopy analysis method is used to solve the transformed differential equations. The neural computing strategy is employed to find results in a more concise form that is more precise and validated. The Carreau fluid assessment in terms of the thin film nanofluid over a disk is a novel idea, and the combination of three methods is very rare to study the thin film nanofluid flow over a rotating disk. The outcomes show that the convective heat transfer is substantially increased using the thin film of the Carreau nanofluid. It has been observed that Carreau nanofluid can effectively regulate the temperature during thin film deposition. The ANN technique and existing literature were utilized to observe the validation of the Carreau nanofluid liquid film.
