Application of the k-omega turbulence model to estimate the flutter derivatives of a long-span bridge

2011
This paper considers the influence of the turbulence model adopted to numerically predict the aero-elastic phenomena in Fluid Structure Interaction (FSI) problems. After a detailed evaluation of the main suitable turbulence models available in the Reynolds Average Navier Stokes (RANS) approach, the two-equation k-ω turbulent model was identified ...

A new non‐equilibrium modification of the k−ω$$ k-\omega $$ turbulence model for supersonic turbulent flows with transverse jet

International Journal for Numerical Methods in Fluids
AbstractThe goal of this research is to propose a new modification of a non‐equilibrium effect in the turbulence model to better predict high‐speed turbulent flows. For that, the two local compressibility coefficients are included in the balance production/dissipation terms in a specific dissipation rate equation.

Estimation of the flutter derivatives of a long-span bridge using the k-omega turbulence model

2010
The main focus of this paper is to show the Computational Fluid Dynamic (CFD) potentiality about the possibility to estimate the flutter derivatives of a long-span bridge. The Reynolds Averaged Navier-Stokes (RANS) simulation approach is chosen to perform the computations.
