Thermal and solutal transport for chemically reactive flow of Jeffrey nanomaterial

Abstract

This investigation aims to study the behavior of a Jeffery fluid on a stretching surface while considering thermophoresis and Brownian motion effects through Buongiorno's model. The governing equations include thermal and mass transport effects, heat source-sink interactions and chemical reaction rates. Similarity transformations are utilized to solve partial differential equations, transforming them into ordinary differential equations. The bvp5c built-in program in MATLAB is then used to obtain a numerical solution for the ODEs. The study generates graphs to examine how different physical flow parameters affect fluid flow, temperature, and concentration distributions. The graphical analysis shows that mass diffusion decreases as the Brownian parameter and Schmidt number increase, while an increase in thermophoresis and heat source-sink improves thermal transport. The study also explores the influence of various emerging variables on velocity, thermal, and solutal distributions, providing valuable insights into the complex interplay of these factors and contributing to advancing our understanding of fluid dynamics.
