Off‐Centered Stagnation Point, Particle Movement, and Accumulation in a Chemically Reactive Fluid

ABSTRACT The off‐centered stagnation point flow (S‐PF) phenomenon is important in many technical domains where flow patterns affect efficiency and performance. In these systems, the interplay between asymmetric flow and disk rotation influences the temperature boundary layer and concentration gradients, either augmenting or impeding heat and mass transfer rates. Earliest studies focused on stagnation flows or considered only a few thermal or chemical effects, leaving the combined influence of off‐centered asymmetry. Hence, this work fills that gap by examining the significance of thermophoretic particle deposition on the off‐centered S‐PF of fluid via a rotating disk subjected to activation energy. Moreover, the artificial neural network is used to estimate the heat transmission rate as a function of various factors. Increased magnetic field and permeability parameters decrease the momentum field. The concentration profile decreases as the thermophoretic coefficient increases.
