Analysis of Resonance in Jet Screech with Large-Eddy Simulations
Gao Jun Wu, Sanjiva K. Lele, Jinah Jeun
Screech resonance is studied with experimentally validated large-eddy simulation data for a 4:1 rectangular under-expanded jet at three nozzle pressure ratios. The analysis uses sp…
A closure mechanism for screech coupling in rectangular twin jets
Jinah Jeun, Gao Jun Wu, Sanjiva K. Lele
Twin-jet configuration allows two different scenarios to close the screech feedback. For each jet, there is one loop involving disturbances which originate in that jet and arrive a…
Aeroacoustics of Twin Rectangular Jets Including Screech: Large-eddy Simulations with Experimental Validation
Jinah Jeun, Aatresh Karnam, Gao Jun Wu +3
High-fidelity large-eddy simulations (LES) are performed to investigate aeroacoustic characteristics of jets issuing from twin rectangular nozzles with an aspect ratio of 2:1 at tw…
Input-output analysis of Mach 0.9 jet noise
Jinah Jeun, Joseph W. Nichols
We examine amplifying behavior of small perturbations about Reynolds-averaged Navier-Stokes solutions (RANS) of a subsonic turbulent jet using input-output (I/O) analys…
