...° and Froude number Fr = 0.28. The TPIV enables fully volumetric flow measurements and the use of -criteria enables vortex volume visualization and core analysis. The objective of the experiment is to extend the knowledge for the static condition vortex separation onset and progression to unsteady dynamic...

... Results from towing-tank experiments of free-surface wave-induced separation are documented. Free­surface elevations and surface pressures are measured for a surface-piercing NACA0024 hydrofoil progressing into a calm free surface at the Iowa Institute of Hydraulic Research (IIHR) towing tank...

... This project deals with free-surface wave-induced separation on a NACA0024 foil over a range of conditions, along with the validation of the results from the towing tank. The simulations are performed using CFDSHIP-IOWA (a general purpose research code for ship hydrodynamics) and validated using...

This is because it is particularly difficult to accurately determine both the distribution of the velocity over the surface of the hull and the location of the separation lines. The location of the lines of separation...
