As a tribute to the late Professor A. Yücel Odabaşı’s (1945 – 2009) life-long endeavors in promoting the science of Naval Architecture and in particular Naval Hydrodynamics, a biennial international colloquium aiming to focus on a different theme on each occasion, gathering specialists from around the world, was organized. The theme of the third colloquium in the series is selected as “Progress in Propeller Cavitation and its Consequences – Experimental and Computational Methods for Predictions”. In this colloquium, the recent developments in experimental and computational methods for predicting propeller cavitation performance of surface vessels and submarines will be discussed.
