non-axisymmetric turbulent jets using spectral proper orthogonal decomposition (SPOD) is …

An experimental study is conducted on unsteady pressure fluctuations occurring near the
nozzle exit and just outside the shear layer of compressible jets. These fluctuations are …

We perform a computational study on the effects of localized arc filament plasma actuator
based control on the flow field and acoustics of a supersonic 2: 1 aspect ratio rectangular jet …

An empirical closure model of rectangular twin jets' screech and coupling has been
developed to predict their coupling mode at a given flow condition. It builds on Powell's …

Large eddy simulations of supersonic jets from a twin rectangular nozzle are performed with
the GPU-accelerated version of Cascade's charLES" compressible flow solver. Comparisons …

Supersonic jets are known to produce complex flow fields containing high levels of
turbulence, thin shear layers with large gradients, and elevated noise levels. One of the …

Supersonic rectangular twin jets (RTJ) are of interest for current and future generations of
tactical aircraft. However, the adverse effects of coupling have previously been documented …
