The synergistic use of experiments and numerical simulations can uncover the underlying physics of airframe noise sources. We focus on the high-lift noise component associated with a leading-edge...
M. Khorrami, B. Singer, D. Lockard, Mehdi R. Khorrami, Bart A. Singer, David P. Lockard
Unsteady computational simulations of a multi-element, high-lift configuration are performed. Emphasis is placed on accurate spatio-temporal resolution of the free shear layer in the slat-cove...
Aeroacoustic Experiments in the Langley (2002)
Craig L. Streett, Guy R. Neubert, Robert W. Stoker, James R. Underbrink, Mert E. Berkman, Mehdi R. Khorrami, ...
A phased microphone array was used in the Langley Low-Turbulence Pressure Tunnel to obtain the radiated acoustic field from high-lift wing configurations that included a slat and a part-span flap....
A Novel Approach for Reducing Rotor Tip-Clearance Induced Noise In Turbofan Engines (2001)
Fei Li, Th Aiaa/ceas Aeroacoustics, Mehdi R. Khorrami, Meelan Choudhari
Rotor tip-clearance induced noise, both in the form of rotor self noise and rotor-stator interaction noise, constitutes a significant component of total fan noise. Innovative yet cost effective...
Computational Aeroacoustic Analysis of Slat Trailing-Edge Flow (1999)
Th Aiaa/ceas Aeroacoustics, Bart A. Singer, David P. Lockard, Kenneth S. Brentner, Mehdi R. Khorrami, Mert E. Berkman, ...
this paper will conform to the schematic of the experimental setup shown in Fig. 1. The view in Fig. 1 has been rotated from the physical orientation to one that is more intuitive. An enormous amount...

On the Effects of Viscosity on the Stability of a Trailing-Line Vortex. (1998)
Duck, Peter W., Khorrami, Mehdi R.
The linear stability of the Batchelor (1960) vortex is investigated. Particular emphasis is placed on modes found recently in a numerical study by Khorrami (1991). These modes have a number of...
Sensitivity Analysis of Hydrodynamic Stability Operators. (1998)
Schmid, Peter J., Henningson, Dan S., Khorrami, Mehdi R., Malik, Mujeeb R.
The eigenvalue sensitivity for hydrodynamic stability operators is investigated. Classical matrix perturbation techniques as well as the concept of epseudoeigenvalues are applied to show that parts...
