Hydrodynamic Performance of Flapping-foil Propulsion in the Influence of Vortices
flapping-foil vortex numerical simulation hydrodynamic performance save energy
2011/9/9
Fish are able to make good use of vortices. In a complex flow field, many fish continue to maintain both efficient cruising and maneuverability. Traditional man-made propulsion systems perform poorly ...
A comparison of the performance of 4D-Var in an explicit and implicit version of a nonlinear barotropic ocean model
4D-Var explicit and implicit version nonlinear barotropic ocean model
2009/11/3
A comparison is made of the performance of the four-dimensional variational data assimilation (4D-Var) method in an explicit and implicit version of a barotropic quasi-geostrophic model of the wind-dr...
Modeling Spectral Dissipation in the Evolution of Wind Waves. Part I:Assessment of Existing Model Performance
Wind Waves Modeling Spectral Dissipation Existing Model Performance
2008/12/16
This study examines the performance of a state-of-the-art spectral wind wave model that uses a full solution to the nonlinear interaction source term. The situation investigated here is fetch-limited ...
