Numerical Investigation of Transonic Resonance with a Convergent-Divergent Nozzle

Computation of Tone Noise from Supersonic Jet Impinging on Flat Plates

“…The recent space-time conservation element and solution element method (CE/SE) [12][13] is a MILES type finite volume method with generally less numerical dissipation and is adopted for the computation. As demonstrated in previous papers, the CE/SE scheme is well suited for aeroacoustics computation [15,16]. Because of the CE/SE non-reflecting boundary conditions (NRBC), which are based on the physics of plane wave propagation [14], a smaller near field computational domain can be used in the present numerical simulation and helps to save both memory and CPU time.…”

Computation of Low Speed Cavity Noise

“…There are various variants of the NRBCs [9][10][11][12][13][14], the following are the ones employed in this paper.…”

On Space-Time Inversion Invariance And Its Relation To Non-Dissipatedness Of A CESE Core Scheme

“…The physical phenomena modeled include traveling and interacting shocks, acoustic waves, vortex shedding, viscous flows, detonation waves, cavitation, flows in fluid film bearings, heat conduction with melting and/or freezing, electrodynamics, MHD vortex, hydraulic jump, crystal growth, and chromatographic problems . In particular, the rather unique capability of the CESE method to resolve both strong shocks and small disturbances (e.g., acoustic waves) simultaneously [13,15,16] makes it an effective tool for attacking computational aeroacoustics (CAA) problems. Note that the fact that second-order CESE schemes can solve CAA problems accurately is an 1 exception to the commonly-held belief that a second-order scheme is not adequate for solving CAA problems.…”
