A real-time flow visualization system that produces 17 images over a time span of 150 ms is used to visualize the mixing layers of Mach 1.3 (M c50.59) and Mach 2.0 (M c50.87) ideally expanded high Reynolds number axisymmetric jets. These image sequences reveal details about the influence of compressibility on the dynamics of turbulence structures. In general, the behavior observed in axisymmetr...

Axisymmetric standing waves occur across a wide range of free surface flows. When these reach critical height (steepness), wave breaking and jet formation occur. For travelling gravity waves, is generally considered to limit reversible motion. In the ocean, behaviour directionally spread lies between limits purely (two dimensions) axisymmetric (three dimensions). Hence, understanding on an impo...
