Computational Aeroacoustic Analysis of Slat Trailing-Edge Flow
A Singer Bart,P Lockard David,S Brentner Kenneth,R Khorrami Mehdi,E Berkman Mert,Choudhari Meelan +5 more
TL;DR: In this article, an acoustic analysis based on the Fowcs Williams and Hawkings equation was performed for a high-lift system using unsteady flow data obtained from a highly resolved, time-dependent, Reynolds-averaged Navier-Stokes caclulation.
Proceedings ArticleDOI
Simulations of Bluff Body Flow Interaction for Noise Source Modeling
Medi R. Khorrami,P Lockard David,Meelan M. Choudhari,Luther N. Jenkins,Dan H. Neuhart,Catherine B. McGinley +5 more
TL;DR: In this article, the authors extended their previous two-dimensional, unsteady, Reynolds Averaged Navier-Stokes computations to three dimensions using a quasilaminar, zonal approach, in conjunction with a two-equation turbulence model.
Proceedings ArticleDOI
A High-Order Method Using Unstructured Grids for the Aeroacoustic Analysis of Realistic Aircraft Configurations
L Atkins Harold,P Lockard David +1 more
TL;DR: The discontinuous Galerkin method provides a framework for the development of a high-order method using unstructured grids and its compact form contributes to its accuracy and efficiency, and makes the method well suited for distributed memory parallel computing platforms.
An Application of the Quadrature-Free Discontinuous Galerkin Method
P Lockard David,L Atkins Harold +1 more
TL;DR: The quadrature-free discontinuous Galerkin method is applied to a two-dimensional shear layer problem and has been demonstrated to possess the accuracy required for acoustics even in cases where the grid is not smooth.
