The results of a study of the near-wall flow of air in a vortex chamber with an end-wall swirler by the method of oil-flow visualization are presented. The influence of the mass flow rate on a near-wall flow of the vortex chamber is studied. The experimental results demonstrate the presence of separation flow on the cylindrical surface near the blind end-wall, and the non-uniformity of the near-wall flow on the end-wall with swirler. It is shown that when increasing the mass flow rate, the separation zone shifts to the blind end-wall, and its width decreases. In addition, distributions of the swirl angle of the flow on the cylindrical wall along the height of the chamber are obtained.
