Three-Dimensional Jet Issuing from the Cruciform Nozzle : 4th Report, Statistical Characteristics

Statistical characteristics of a three-dimensional jet issuing from a cruciform nozzle have been examined experimentally to clarify the features of the present flow field due to the secondary flows. In the extent of x/d≥50 where the mean velocity profile U/U ox shows the similarity, the ratio of the integral length scales L u /L v on the x axis assumes a constant value
