Numerical Simulation of the Flow-Sound Interaction Mechanisms of a Single and Two-Tandem Cylinders in Cross-Flow
Atef Mohany,Samir Ziada +1 more
TL;DR: In this paper, a numerical simulation of the flow-excited acoustic resonance for the case of two-tandem cylinders in cross-flow is performed, where the main aeroacoustic source, which causes a positive energy transfer from the flow field to the acoustic field, is found to be located just downstream of the cylinder.
Journal ArticleDOI
An improved visualization-based force-measurement technique for short-duration hypersonic facilities
TL;DR: The limitations of an improved version of a recently proposed visualization-based technique for the measurement of forces and moments in short-duration hypersonic wind tunnels based on tracking the motion of a free-flying body over a sequence of high-speed visualizations are described and explored.
Journal ArticleDOI
Structured and Unstructured Computations on the DLR-F4 Wing-Body Configuration
TL;DR: The performance of the DLR structured and unstructured computational fluid dynamic (CFD) codes in predicting aircraft forces and moments on a wing-body configuration at transonic speeds is investigated in this article.

URANS Computations of Shock-Induced Oscillations Over 2D Rigid Airfoils: Influence of Test Section Geometry
Mylène Thiery,Eric Coustols +1 more
TL;DR: In this paper, the authors deal with recent numerical results from on-going research conducted at ONERA/DMAE regarding the validation of turbulence models for unsteady transonic flows, in which the mechanism of the shockwave/boundary-layer interaction is important.

Reassessment of the scale-determining equation for advanced turbulence models
TL;DR: In this paper, a two-equation turbulence model is proposed that is shown to be quite accurate for attached boundary layers in adverse pressure gradient, compressible boundary layers, and free shear flows.

Direct simulation of a turbulent boundary layer up to R sub theta = 1410
TL;DR: In this paper, the turbulent boundary layer on a flat plate, with zero pressure gradient, is simulated numerically at four stations between R sub theta = 225 and R sub tta = 1410.

A mathematically simple turbulence closure model for attached and separated turbulent boundary layers
D. A. Johnson,L. S. King +1 more
TL;DR: In this article, a new turbulence closure model was proposed to treat two-dimensional, turbulent boundary layers with strong adverse pressure gradients and attendant separation by using an ordinary differential equation derived from the turbulent kinetic energy equation to describe the stream wise development of the maximum Reynolds shear stress in conjunction with an assumed eddy viscosity distribution.

Artificial dissipation and central difference schemes for the Euler and Navier-Stokes equations
R. C. Swanson,Eli Turkel +1 more
TL;DR: In this paper, an artificial dissipation model, including boundary treatment, that is employed in many central difference schemes for solving the Euler and Navier-Stokes equations is discussed.
