A Study on Interacting Free Jets

Abstract

Structures of interacting free jets from two sonic nozzles are studied by flow visualization for various angles between centerlines of nozzles and various ratios of the source pressure P_s. to the pressure in the expansion chamber P_b. Experiments are carried out with I₂-seeded Ar which easily radiates fluorescence by irradiation of a laser beam. Characteristic shock systems and density distributions of the interacting two free jets are qualitatively elucidated from the analysis of many photographs of visualized entire flow fields.
