(Special Issue: Tony Maxworthy) Influence of Chemical and Radiation on an Unsteady MHD Oscillatory Flow using Artificial Neural Network (ANN)
Authors: ,
Abstract: This paper delves into the intricate interplay between chemical and thermal radiation in the context
of an unstable magnetohydrodynamic(MHD) oscillatory flow through a porous medium. The fluid under
investigation is presumed to be incompressible, electrically conductive, and radiating with the additional
influence of a homogeneous magnetic field applied perpendicular to the channel’s plane. Analytical closedform
solutions are derived for the momentum, energy, and concentration equations providing a comprehensive
understanding of the system’s behavior. The investigation systematically explores the impact of various flow
factors, presenting their effects through graphical representations. The governing partial differential equations
(PDE) of the boundary layer are transformed into a set of coupled nonlinear ordinary differential equations
(ODE) using a closed-form method. Subsequently, an artificial neural network (ANN) is applied to these
ODEs, and the obtained results are validated against numerical simulations. The temperature profiles exhibit
oscillatory behavior with changes in the radiation parameter (N), revealing insights into the system’s dynamic
response. Furthermore, the paper uncovers that higher heat sources lead to increased temperature profiles.
Additionally, concentration profiles demonstrate a decrease with escalating chemical reaction parameters, with
a reversal observed as the Schmidt number (Sc) increases. This study highlights the efficacy of an ANN model
in providing highly efficient estimates for heat transfer rates from an engineering standpoint. This innovative
approach leverages the power of artificial intelligence to enhance our understanding of complex fluid
magnetohydrodynamics and porous media flows.
