EXPERIMENTAL INVESTIGATION OF FLOW AROUND A MARINE PROPELLER AND APPLICATION OF PANEL METHOD TO THE PROPELLER THEORY

Flow around a marine propeller was investigated experimentally. Measurement of pressure distributions on blades of model propellers was performed in a cavitation tunnel. Measurement of velocity distribution around propeller blades was also carried out using an LDV (Laser Doppler Velocimeter) measurement system. The investigation into the measured velocities revealed the vortex system around propeller blades. Experimental results were compared with the results calculated by the ordinary theoretical method based on the lifting surface theory. The comparison shows that it is necessary to take into account the three dimensional blade thickness effect and the separated flow in the region near the blade tip. The development of a propeller theory based on a panel method is presented to improve on the ordinary theoretical method.
