The coherent structure in the near-field of an axisymmetric turbulent jet at a Reynolds
number of 3.8× 105 and Mach number of 0.3 is experimentally characterized by a vector …

An experimental investigation into the flow-field of a modern jet nozzle has been carried out.
Even in canonical flows (eg axisymmetric jets), turbulence and its consequences are not …

The spatiotemporal dynamics of the coherent structures in an under-expanded supersonic
impinging jet are studied using a spectral proper orthogonal decomposition technique. For …

Earlier experiments on turbulent jets (Crow and Champagne, 1 Brown and Roshko2) made
clear that large structures dominated the physics of the axisymmetric jet. Although no clear …

The present article deals with the spatiotemporal reduction of a reacting, supersonic,
turbulent jet. A flowfield dataset is first obtained from a LES simulation including chemical …

A Proper Orthogonal Decomposition (POD) is constructed for a Mach 0.9 turbulent jet using
a well-validated direct numerical simulation database. Norms are defined based on near …

Abstract The Proper Orthogonal Decomposition (POD) is used in the present work to study
