[12], annular jet impingement onto a conical cavity and heat transfer rates from the cavity surfaces were examined for various jet velocities, two outer angles of the annular nozzle, and two cavity depths.

Flow-field characteristics of high-temperature annular buoyant jets and their development laws influenced by ventilation system

The result shows the exit flow acquires radial velocity components due to the presence of swirl diverging radially as soon as it exits the annular nozzle. The flow field of swirl jet shows that increased uniformity in the radial velocity component with respect to nozzle axis.
