The objective of the study is to investigate fluid flow and heat transfer characteristics applying Artificial Neural Networks (ANN) analysis in triangular-shaped cavities for magnetohydrodynamics (MHD) mixed convection with varying velocity water/Al 2 O 3 nanofluid. No has yet been conducted on this geometric configuration incorporating ANN analysis. Therefore, analyzes predicts complex interactions among flow, transfer, various influencing factors using process finite element was conducted, obtained results have verified by previous literature. Levenberg-Marquardt backpropagation technique selected ANN. Various values Richardson number (0.01 ≤ Ri 5), Hartmann (0 Ha 100), Reynolds (50 Re 200), solid volume fraction nanofluid (ϕ = 1%, 3% 4%) selected. model incorporates Gauss-Newton method damped least squares, making it suitable tackling problems a high degree non-linearity uncertainty. findings shown through use streamlines, isotherm plots, Nusselt numbers, estimated Increasing improves rate transmission all situations Ri, Re, Ha. greater larger parameters, but lessens higher value Furthermore, demonstrates exceptional precision, as evidenced Mean Squared Error R 1.05200e-6 0.999988, respectively.

The study of natural convection and heat transfer in a trapezoidal cavity finds wide range technological applications including thermal energy storage systems, building ventilation/insulation, waste recovery, electronic device cooling, controlling PV panel temperature, conservation, exchangers, nuclear reactors, furnaces, glass production, food processing, drying technologies. purpose the current is to explore entropy non-Newtonian nanoenhanced phase change material (NEPCM) suspension saturated porous medium enshrouded trapezoid-shaped domain with three heated blocks fitted bottom surface. novelty present work introduction power-law (Ostwald-de Waele) model subject NEPCM enclosure emplacing fins at its surface embedded Brinkman-Forchheimer extended Darcy variant porosity. finite element method implemented solve governing equations numerically. important findings include streamlines, isotherms, velocities, apparent viscosity enhance while generation whittles down rise number. Entropy ameliorates by 519.16% for low high porosity medium. maximum augments 1441.24% when power law index ameliorates.
