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://lecoureures.shop/product-category/course-a-pied-homme-chaussures-sentier/
