Flow visualization and numerical study of a slot jet in a horizontal channel partially filled with FeCrAlY foam is carried out to observe the flow structure under buoyancy effect. The flow patterns in the fluid region for different jet velocity (0 <= Pe <= 548.9) are captured using particle imaging velocimetry. The flow patterns obtained from simulations are similar to the experimental results. The flow patterns for 219.5 <= Pe <= 548.9 with buoyancy strength of Ra = 1.024 x 10(6) and Ra = 1.048 x 10(6) for dimensionless height of 0.6 and 0.8, respectively, demonstrated mixed convective flows. Buoyancy driven roll is observed near the edge of the metal foam, and jet driven roll is observed above the metal foam.
