Development and Verification of a Computational Fluid Dynamics Model of a Horizontal-Axis Tidal Current Turbine
This paper describes the development of a computational fluid dynamics (CFD) methodology to simulate the hydrodynamics of horizontal-axis tidal current turbines. Qualitative measures of the CFD solutions were independent of the grid resolution. Conversely, quantitative comparisons of the results ind...
