Navier–Stokes solvers in European aircraft design
TL;DR: A broad perspective of the progress made during the last 10 years in solving the Navier-Stokes equations is given and how this simulation technique went from being a specialized research topic to a practical engineering tool that design engineers use on a routine basis is traced.

Aerodynamic Analysis of Blunt Trailing Edge Airfoils
Kevin Standish,C. P. van Dam +1 more
TL;DR: In this article, the inboard region of large wind turbine blades is analyzed using computational fluid dynamics, including a viscous/inviscid interaction method and three Reynolds-averaged Navier-Stokes methods.

An improved criterion to select dominant modes from dynamic mode decomposition
Jiaqing Kou,Weiwei Zhang +1 more
TL;DR: In this article, a criterion to select dominant modes from DMD technique is developed, which considers the evolution of each mode within the whole sampling space, and ranks them according to their contribution to all samples.
Journal ArticleDOI
Design and analysis of ALE schemes with provable second-order time-accuracy for inviscid and viscous flow simulations
TL;DR: This work considers the solution of inviscid as well as viscous unsteady flow problems with moving boundaries by the arbitrary Lagrangian-Eulerian (ALE) method, and proves that formally second-order time-accurate ALE schemes can be designed.

An evaluation of RANS turbulence modelling for aerodynamic applications
Pietro Catalano,Marcello Amato +1 more
TL;DR: In this paper, the authors applied the CIRA RANS flow solver by employing a large set of turbulence models, to typical aerodynamic applications for which certified experimental data are available in literature.

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.

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.
