| Abstract | ||||
| Heat transfer and pressure drop were measured for flow of air through a horizontal tube filled with porous media with internal induction heat generation. The heated copper test section has an inside diameter of 0.02 m, and 0.225 m long. The porosity was varied from 0.2527 to 0.5251 using uniform spherical steel beads. These beads are internally heated by passing alternative current through an induction coil wrapped around the tested tube. Over the range of 250<Re<10600, and Gr=1.2x107, the friction factor data agreed with the Newtonian prediction. Heat transfer increases with increasing Reynolds number and decreasing porosity. A new experimental correlation were proposed for predicting the heat transfer and friction factor of fluid flow through confined porous media. | ||||
