The azimuthal correlations of velocity and temperature fluctuations in an axisymmetric jet

Research output: Contribution to journalArticle

Abstract

The structure of turbulence in an axisymmetric jet at the nozzle exit Reynolds number of 4 X 104 was examined at several streamwise stations (1.0 ≤ x/D ≤ 40), by measuring, for a few fixed radial positions, two-point correlation functions of the streamwise velocity and temperature fluctuations with azimuthal separation. By an orthogonal Fourier decomposition of the azimuthal correlation functions, an interpretation of these correlations and of the large-scale evolution is provided.
