Time evolution of the shear layer of a supersonic axisymmetric jet at matched conditions
Abstract
A two-laser two-detector experiment was used to investigate the temporal evolution of the mixing layer of a pressure-matched supersonic jet at an exit Mach number of 1.5, discharging into still air. The convective speed of the structures present in the flow were measured and compared with previous findings. Additional views of the mixing layer provide information on the three-dimensionality of the mixing layer. The structures travel with a velocity higher than the predicted velocity and they rotate.
