Numerical heat transfer analysis of a thermal energy storage system enclosure with horizontal fin for sustainable energy storage

Two-dimensional numerical analysis is carried out in a square cavity with extended surface with nanofluid foe heat transfer enhancement under natural convection in a laminar flow regime. Pure water, ethylene glycol (EG), Water/EG mixture (20%, 40%, 60% and 80%) with aluminium oxide concentration of...
