Computational analysis of mixed convection in a square cavity with a corrugated curved heating wall using finite element and Bayesian regularized artificial neural network approaches
The mixed convection heat transfer properties of a square enclosure with a rotating cylinder in the middle are examined in the current work. Examining the combined effects of the Rayleigh number, heated length along the curved base, and rotating Reynolds number on flow structures, heat distribution, and overall heat transfer performance is the main objective. This study's objective of expanding our understanding of these related buoyancy and rotational characteristics, which are essential to raising the thermal efficiency of tiny cooling devices and energy systems, is what makes it special and pertinent. The Galerkin finite element technique in the COMSOL Multiphysics 6.3 framework with artificial neural network methodology is used to numerically solve the model equations of the conservation of mass, momentum, and energy in a two-dimensional laminar flow model set in the Boussinesq approximation. The quantitative results and the Artificial Neural Network (ANN) model outputs show a strong association. The "Bayesian regularization" (BR) algorithm of ANN shows the highest accuracy of the results. The results show that the asymmetric vortex structures occur mostly because of the rotation used and that mixing of fluids was enhanced by the rotation, and the Nusselt numbers were higher than in the case of a static system, especially at higher Rayleigh numbers and in longer heated lengths along the curving bottom. Furthermore, the study results indicate that the FEM and ANN methodologies could provide a quicker and more accurate assessment of thermal properties, and this approach appears to be a particularly suitable strategy for real-time applications in heat exchangers, electronic cooling systems, and solar thermal collectors, whereby efficient heat transfer under mixed convection conditions is a necessity
In this paper, we investigate a (2+1)-dimensional noncommutative coupled dispersionless (CD) system with variable coefficients.
A challenging task in studying geometric function theory is determining the sharp estimates for coefficient-related results that come up in the Taylor series of analytic univalent functions.
