The study of entropy generation in thermal non-equilibrium (TNE) states has significant implications for optimizing management systems and understanding heat transfer mechanisms permeable media. This investigates the properties a state within double-lid-driven enclosures filled with medium. Unlike temperature equilibrium state, approach is described by two equations: one irreversibility mixture phase medium phase. High mixed convection considered due to motion non-facing edges (left-side upper edges). Four cases based on direction are examined: Case 1, where left-side top move negative positive directions Y- X-axes, respectively; 2, X- Y-axes, Cases 3 4, respective axes. Heat flow domain both suspension phases. governing system solved numerically using finite volume techniques SIMPLER algorithm. obtained data used predict key quantities, such as rate, under influence major factors an effective artificial neural network (ANN) analysis. main findings show that solid higher compared other cases. Additionally, 2 results minimum Nusselt coefficient at center active boundary.
