Purpose Nano-encapsulated phase change materials (NEPCMs) are favourable in terms of their potentials to ameliorate the efficiency working liquids, keeping apparatus at a determined cooling temperature. NEPCMs used thermal management buildings, air-conditioning systems and electronic devices. Because notable temperature disparity among two components (solid as well nanofluid) linear/non-linear porous material, an interface model such local non-equilibrium (LTNE) is highly applicable equipment, geothermal engineering high-conductivity foams. Forchheimer-Brinkman-extended Darcy (FBEDM) featured with fluid flow higher velocities high porosity medium significantly found solar systems, heat exchangers condensation boiling operations. In view above real-world applications NEPCMs, LTNE FBEDM, aim this work scrutinize effect on hydrothermal features buoyancy-driven suspension inclined square chamber subject FBEDM. The introduction mechanism horizontal displacement vertical (VD) channels domain, FBEDM novelty work. Design/methodology/approach equations govern problem solved via finite element method irreversibility (nanofluid solid) structure also explored. Findings important findings study that mean Nusselt numbers nanofluid matrix phases peter out by 15.71% 29.6% rise VD from 0.3–0.6 while those whittle down 23.73% 44.12% HD 0.3–0.7. Average Bejan number reduces 8.69% 0.93% amplification cavity inclination angle (a) 0° 30° 60° it enhances 3.79% increase 90°. Originality/value Although there some theoretical experimental studies NC nano-encapsulated PCMs, exist limited altogether which geometrical parameters’ roles have been analyzed. This first examine influence HD, entropy specifications
