An experimental study has been carried out for an air jet with swirl discharging from a nozzle along a solid surface. Mean and fluctuating velocities are measured by rotating a probe with an inclined hot wire. Flow pattern of mean and secondary stream in cross section and distribution of Reynolds stress are shown, and physical explanations are offered for phenomena peculiar to the wall jet with swirl. The experimental results are compared with the existing ones on the air jet with swirl coming into stagnant-air surroundings, and the effects of the solid surface on the jet are elucidated.
