This study examines the characteristics of activation energy on the two-phase flow of a tri-hybrid nanofluid with variable thermal conductivity. viscous dissipation. and NHCMBM using a stochastic-based Levenberg-Marquardt backpropagated neural network (LMB-NN). The Darcy Forchheimer porous media characteristics is included in the momentum equation. https://www.shoptracepaper.com/product-category/jewelry/
