概要

• 論文の詳細を見る

• 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. In the relatively upstream portion, both the skewness factors S(u) and S(v) show a negative value, while both the flatness factors F(u) and F(v) take a positive value. The turbulent large eddy structure conjectured from the space-time correlation is significantly different at each location throughout the cross section.
