The current photo (frame) focuses on the experimental investigation of the turbulent buoyant jet mixing process when injected through a circular nozzle into a confined ambient fluid. The ambient fluid inside the tank is initially homogeneous and stagnant. The jet fluid is injected through a nozzle located at the top of the tank and has a slightly larger density than the ambient fluid. The jet moves vertically downwards driven by its initial momentum and buoyancy forces. Once the jet reaches the bottom of the tank, it diffuses horizontally up to the side walls of it.
