【Abstract】

<正>We present a dynamic mode decomposition of the composite vorticity-dilatation fields from linearized simulations of a compressible, axisymmetric jet emanating from a modeled nozzle. A subdomain analysis concentrates on the shear layer emanating from the nozzle wall and the far-field dominated by acous-
