An Eigenfunction Analysis of Axisymmetric Jet Flow

The rnapshot method is used to analyze a large eddy simulation of axisymmetric jet flow. An ensemble of realizations is collected using a sampling condition that corresponds to the passage of a large scale vortex at a position six diameters downstream from the nozzle. The analysis is performed separately on a variable composed of the primitive flow quantities and the mass fraction of the materi...

A Pulsed, Precessing Jet in Cepheus A

We present near-infrared H2, radio CO, and thermal infrared observations of the nearby massive star-forming region Cepheus A (Cep A). From H2 bow shocks arranged along four distinct jet axes, we infer that the massive protostellar source HW2 drives a pulsed, precessing jet that has changed its orientation by about 45 in roughly 104 years. The current HW2 radio jet represents the most recent eve...

Compressibility Effects on the Growth and Development of Large-Scale Structures in an Axisymmetric Jet

A temporally resolved flow visualization system that produces 17 flow images over a time span of 128 microseconds is used to visualize the mixing layers of a Mach 1.28 (M c =0.59) and a Mach 2.06 (M c =0.87) ideally expanded high Reynolds number axisymmetric jets. These image sequences revealed details about the effects of compressibility on the dynamics of turbulence structures. In general, th...
