Abstract

The flow field of a supersonic free jet is investigated both numerically and experimentally. Two-dimensional axi-symmetric numerical code is developed and applied to a nozzle geometry, which is equivalent to the nozzle used in the experiment. Experiments of flow visualization are also carried out with a simple nozzle geometry. Acetone laser-induced fluorescence (Acetone LIF) is used to visualize cross sections of the flow field induced by supersonic jets. A conventional optical visualization technique with a high-speed video camera is also used.
