Smoke-wire visualization provides insight into the flow structure of round jets issuing from straight tubes and impinging on concave and convex surfaces with high relative curvature values. The technique provides a crosssectional view of the jet, allowing the imaging of the initiation and growth of ring vortices in the jet shear layer and their subsequent interaction following impingement on the cylindrical surfaces. Both photographic and video records of the flow are obtained. Effects of relative curvature, nozzle-to-surface distance and Reynolds number on the impinging jet flow structure are described.
