    Abstract

    Within EU Project SUPERPROP, fishing vessels have been studied. Usually their propulsion units consist of ducted propellers in order to provide large thrust in trawling. Rudders may significantly influence the performance of ducted propellers especially if they are located at short distance from the duct. This paper summarizes some of the CFD calculations performed as the starting point for the development of a new propeller design for a reference fishing boat. The basic design performance particulars were obtained from the analysis of the existing conventional ducted propeller installed in the ship. The flow around the original propeller geometry and around one of the alternative designs is simulated using RANS code FINFLO. As a part of the project the rudder blockage effect has been investigated using a quasi-steady approach.
