The flow past grooves or cavities in offshore structures results in undesirable noise and oscillations. An experimental study, using optical anemometers, of the fluid motion induced in the grooves by an adjacent stream is presented. The structure of the vortex system within the enclosures, its dependancy on the aspect ratios of the geometry and the type of oscillation generated are examined. The experimental information is used to verify numerical predictions of the measured quantities. The performance of the turbulence models in simulating these complex flows is also assessed. © 1992.
