ABSTRACT
Detailed particle image velocimetry measurements have been made to characterize the flow around a keel/bulb geometry. These measurements are used to evaluate the closure assumptions of two typical turbulence models: the eddy-viscosity SST model and the second-moment model BSL-w-RSM. The experiments are conducted in a low speed wind tunnel. Measured flow parameters include the mean velocity profiles and the Reynolds stress tensor. Both turbulence models are shown to perform well regarding mean velocity and global predictions. Turbulence data predictions, however, are shown to be, in some cases, erroneous by at least one order of magnitude.
