Journal ArticleDOI
Critical Hypersonic Aerothermodynamic Phenomena
TL;DR: Considerable work still needs to be done before the understanding of hypersonic flow will allow for the accurate prediction of vehicle flight characteristics throughout the flight envelope from launch to orbital insertion.
ReportDOI
WIND: The Production Flow Solver of the NPARC Alliance
TL;DR: The approach taken in managing this joint software development project is described, an outline of the flow solver capabilities, a brief overview of the solution procedure, and some example simulations are described.
Journal ArticleDOI
Numerical investigations of flow over a sphere in the subcritical and supercritical regimes
TL;DR: In this paper, the Strouhal number, St, associated with large-scale shedding is predicted at St∼0.195 along with a higher frequency component associated with the development of the Kelvin-Helmholtz instabilities in the detached shear layers.
Proceedings ArticleDOI
Numerical simulation of synthetic jet actuators
TL;DR: In this article, a two-dimensional, incompressible simulation of synthetic jet actuators is performed and three different velocity distributions along the orifice are examined and all three distributions give qualitatively similar flow features.
Journal ArticleDOI
Thirty years of development and application of cfd at boeing commercial airplanes, seattle
TL;DR: A chronology and issues related to the acquisition, development, and use of Computational Fluid Dynamics (CFD) at Boeing Commercial Airplanes in Seattle can be found in this paper.

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.
Journal ArticleDOI
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.
