Characterization of cavitation during the closing of mechanical (heart) valves

The goal of this project is to investigate the influence of turbulent fluctuations on the pressure distribution, drag and the resulting deformation of flexible floating structures. Examples of such structures are floating offshore solar farms, floating inflatable breakwaters, and floating foundations for offshore wind turbines. Due to their large dimensions, the formation of a (turbulent) boundary layer is commonly neglected in their assessment and simulation in waves. For conventional offshore structures with considerable stiffness, we deem this approach feasible. However, with new and much more flexible structures considered for floating solar platforms, the wavelength of local structural deflections becomes much smaller and boundary layer effects may become quite significant. To quantify these effects experimentally, we will employ techniques based on Particle Image Velocimetry (PIV) combined with Digital Image Correlation (DIC) and apply them to model tests in the flume and towing tanks of ME.
