Experimental investigation of heat transfer and pressure drop in metal-foam-filled circular and flattened tubes

Heat transfer and pressure drop of laminar flow inside circular and flattened tubes partially and fully filled with copper metal foam were experimentally investigated. The wall heated by a constant and uniform heat flux and water was used as the working fluid with Reynolds number ranging 500–2300. Six different configurations for tubes and porous media supposed and the Nusselt number and pressure drop data are reported and compared. The...
