Abstract
One of the advantages of Computational Fluid Dynamics over traditional model testing is the capability
to predict Reynolds-number effects on the flow field around a ship. In earlier numerical studies, successful results have been presented in computing ship stern flows from model up to full scale Reynolds number, with verification of numerical errors. Apart from the numerical accuracy, however, it is important to compare the predicted flow fields with experimental results. In this paper a validation study is presented of the wake field of the St. Michaelis product tanker at model and full scale Reynolds number. Experimental results obtained with laser-Doppler anemometry are available for this vessel at both Reynolds numbers. The steady double-body flow field at zero drift angle is simulated with two turbulence models. These are Menter's one-equation model, extended with the correction by Dacles-Mariani et al., and Menter's k - w model.
