摘要 Using smoke and sheet laser source, at different Reynolds numbers, the flow profiles at various positions from the round jet exit are visualized, and the developing process of the large eddy structure of the round turbulent jet is observed. This work paves the way for the further study of two phase turbulent coherent structure.
