Analysis of Temperature‐Induced and Heat‐Driven Diffusion Off‐Centered Stagnation Point Flow

ABSTRACT The investigation of temperature‐induced and heat‐driven diffusion effects on the off‐centered stagnation point flow (OSF) of non‐Newtonian fluid (NNF) across a rotating disk (RD) has considerable applications in industries, including concurrent heat and mass transfer. The applications include polymer extrusion, chemical vapor deposition, petroleum refining, and heat management systems using NNFs. Inspired by this, the present work investigates the Dufour and Soret consequences on the OSF of Maxwell fluid via an RD. Additionally, the influence of thermophoresis and Brownian motion is considered to assess the mass and heat transport attributes. The governing differential equations are converted into ordinary differential equations by applying the appropriate similarity transformations. Furthermore, the reduced equations are solved numerically by employing the Runge–Kutta Fehlberg fourth–fifth‐order approach. Moreover, the fluid's profile is evaluated using the artificial neural network technique. The significant outcomes of the study show that the rotation parameter reduces the azimuthal velocity while enhancing the radial velocity. The velocity profile declines as the Maxwell parameter rises. The thermal profile increases with higher values of the Dufour number, thermophoresis, and Brownian motion parameters. The rise in the thermophoresis parameter and the Soret number increases the concentration profile.
