Abstract

In 1998, Ukeiley and Seiner1 presented a set of multipoint x-wire measurements acquired at 6 radial and 19 azimuthal locations covering 180 of a 5.08cm (2) diameter axisymmetric jet at Mach 0.3, 0.6, and 0.85. This experiment provided the single-point statistics, two-point spatial correlation tensor, and the Proper Orthogonal Decomposition (POD) eigenfunctions. A complementary course grid experiment was performed which consisted of mass-flow measurements using 15 x-wires placed at 2 radial and 11 azimuthal locations. These measurements were used in conjunction with the two-point correlation tensor to estimate the instantaneous flow field using Linear Stochastic Estimation (LSE). The estimated instantaneous flow field has been projected upon the eigenfunctions using the Complementary Technique, as described by Bonnet et al.,2 to obtain a time-dependent experimental low-dimensional description of the flow field. Similarities between the findings of Glauser and George3 in an incompressible jet and those of Ukeiley et al.4 and this work at Mach 0.3, 0.6, and 0.85 suggest that the low-dimensional picture of the subsonic jet shear layer is relatively insensitive to variations in Mach or Reynolds number.
