Experimental and numerical investigation of hydroelastic response of a flexible hydrofoil in cavitating flow
TL;DR: In this paper, the authors investigated the fluid dynamics of a flexible NACA66 hydrofoil in cavitating flows by combined experimental and numerical studies, and the results showed that the cavitation has significant effect on the foil deformation and the unsteady characteristics of the hydroelastic response.

Unsteady analysis on the instantaneous forces and moment arms acting on a novel Savonius-style wind turbine
Sukanta Roy,Antoine Ducoin +1 more
TL;DR: In this article, the authors present a transient analysis on the forces acting on a two-bladed Savonius-style wind turbine, and the effect of tip speed ratio on the force coefficients, moment arms and overall turbine performances are observed.

Improved two-equation k-omega turbulence models for aerodynamic flows
TL;DR: In this article, two new versions of the k-omega two-equation turbulence model are presented, the baseline model and the Shear-Stress Transport model, which is based on the BSL model, but has the additional ability to account for the transport of the principal shear stress in adverse pressure gradient boundary layers.

Transition Modelling for General Purpose CFD Codes
TL;DR: An incremental approach was used to validate the model, first on 2D flat plates and airfoils and then on to progressively more complicated test cases such as a three-element flap, a 3D transonic wing and a full helicopter configuration, and good agreement with the available experimental data was observed.
