Publikováno v: International Journal of Aeroacoustics. 20:870-900
Blade vortex interaction noise is a problematic and dominant component of rotor noise. Plasma actuators strategically placed at the tip of the rotor blades can reduce the strength of the tip vortices. This reduction has the potential to significantly

Analysis of supersonic jet turbulence, fine-scale noise, and shock-associated noise from characteristic, bi-conic, faceted, and fluidic injection nozzles
Autor: Trushant K. Patel, Steven A. E. Miller
Publikováno v: The Journal of the Acoustical Society of America. 150(1)
Fine-scale mixing noise (FSMN) and broadband shock-associated noise (BBSAN) are the dominant components of supersonic jet noise in the sideline and upstream directions. We use the previously developed statistical FSMN and BBSAN models to compare the

Statistical sources for broadband shock-associated noise using the Navier-Stokes equations
Autor: Trushant K. Patel, Steven A. E. Miller
Publikováno v: The Journal of the Acoustical Society of America. 146(6)
A decomposition of the Navier-Stokes equations is used to identify the equivalent source term for broadband shock-associated noise (BBSAN). An analytical closed-form model to predict BBSAN is developed using an acoustic analogy based on the Navier-St

A time domain approach for shock noise prediction with decomposition analyses of large-scale coherent turbulent structures in jets
Autor: Steven A. E. Miller, Weiqi Shen, Trushant K. Patel
Publikováno v: Journal of Sound and Vibration. 499:115996
Broadband shock-associated noise (BBSAN) is one dominant component from off-design supersonic jets. A time-domain BBSAN model is proposed and evaluated, which is based on the vector Green’s function solution of the decomposed Navier–Stokes equati
