Towards efficient aerodynamic shape optimization based on the Navier-Stokes equations
Marian Nemec,David W. Zingg +1 more
TL;DR: An accurate and efficient algorithm for Navier—Stokes aerodynamic shape optimization problems is presented and the performance of the new algorithm is demonstrated for several design problems, such as inverse design, lift-constrained drag minimization, lift enhancement and maximization of lift-to-drag ratio.
Journal ArticleDOI
Analysis of the wake dynamics of a propeller operating before a rudder
TL;DR: In this article, the authors analyzed the wake dynamics of a propeller operating before a rudder under open water conditions using a numerical method based on the detached eddy simulation (DES) and explored the evolution mechanism of the propeller wake under different advance coefficient and rudder angle conditions.
Journal ArticleDOI
Investigation of dynamic stall onset
TL;DR: In this paper, the effect of transition on dynamic stall onset was investigated on a 2D-wing model with OA312 airfoil section, where different physical flow phenomena can be identified which are triggering the onset procedure of dynamic stall.
Journal ArticleDOI
Analysis of the interference effects for high-speed catamarans by model tests and numerical simulations
TL;DR: In this article, the authors present the results of a large experimental and numerical campaign aimed to the analysis of the interference effect for a fast catamaran, where data for resistance, sinkage and trim are collected by towing tank experiments for Froude number ranging from 0.2 to 0.8.

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.
