| Abstract | ||
| Experimental and numerical study has been conducted to examine forced convection for air flowing through rectangular duct (10 * 12*100 cm) for vertical and horizontal position; the duct was heated at constant heat flux ranging from (0.2 to 0.54kW/m2). The porous materials were packed by plastic sphere with diameter (4cm). The tests were done for Reynolds number ranged (6913-11433).The results showed that Nusselt number increased with increasing Reynolds number and heat flux for both position. Nusselt number in vertical position is higher at (14%) percent than horizontal and highest at (1.1, 0.91) times than empty duct at vertical and horizontal position respectively. Many experimental correlations have obtained. | ||
