Mixed convection heat transfer and fluid flow through an open-cell aluminium foam around various heat source shapes with constant heat flux inside rectangular horizontal channel, filled with nanofluid is numerically investigated. An open-cell aluminium foam is made of alloy 6101-T6 with porosity 93% and pore densities (10 40) PPI. Nanofluid with three different types of nanoparticles, aluminium oxide (Al 2 O 3 ), copper oxide (CuO) and silicon dioxide (SiO 2 ) with volume fraction of 4% and nanoparticle diameter of (25 nm) dispersed in water are used. Four models of cylindrical shapes are employed as test sections: (model 1) aluminium foam is around a rectangular cylinder = 90 , (model 2) the aluminium foam is around a trapezoidal cylinder shape ( = 82 875 , (model 3) aluminium foam is around a trapezoidal cylinder shape = 75 964 and (model 4) the aluminium foam is around the triangular cylinder shape = 63 435 .In all models, the heat flux is 300 W/m 2 and, aluminium foam length of (5 cm) is used with Reynolds number range of (200-600). The governing equations continuity, momentum and energy are solved by using the Finite-volume method (FVM). The effects of aluminium foam, nanofluid properties and Reynolds number on the Nusselt number and friction factor values, with four models in a rectangular horizontal channel are investigated. The results have shown that higher average Nusselt number is obtained with the use of nanofluid (water + SiO 2 and 40PPI aluminium foam pore density at higher Reynolds number with model (4). Low friction factor is obtained with the use of nanofluid (water + SiO 2 and 10PPI aluminium foam pore density at higher Reynolds number with model (4). Average Nusselt number increases and friction factor decreases when Reynolds number value increases with all models.

“…The thermo-hydraulic performance parameter was found maximum for the relative gap width of 1.0 and the relative gap position of 0.25 (Aharwal et al, 2008). Mohammed et al (2013) studied the effects of geometrical parameters of a corrugated channel within the out-of-phase arrangement. The corrugated channel with three different corrugated tilt angles of 20 o , 40 o , and 60 o with different channel heights of 12.5, 15, and 17.5 mm and different wavy heights of 2.5, 3.5, and 4.5 mm were tested.…”
