- the basic design/selection for the optimal diameter or shaft rotational rate at a given power or thrust, for bollard or sailing conditions;
- scenario analysis for the selected propellers in any operational conditions, including combinator modes and extreme operations, such as crash stop and backing;
- generation of selected propeller geometry both in ITTC standard format, as well as 3-D computer blade models.
After taking user comments about the Beta version on board and integrating them into the new program, the MCD software 1.4 was released in November. The launch was accompanied by a training session during the Vessel Operator Forum at Damen Shipyards, Gorinchem, the Netherlands.
As part of the JIP extension work, the cavitation characteristics of the new propellers were established. The focus on this work was on thrust break down and spindle torque in cavitating conditions. During the JIP several participants conducted their CFD analysis for selected propellers and presented the com- parisons with the measured characteristics. MARIN also conducted extensive analysis with the ReFRESCO code to quantify the scale effects.
E and F-Series Based on the success of the Wageningen C- and D-propeller Series, MARIN is now preparing two new series: the E-Series for Renewable Energy from tidal turbines, and the F-Series for modern fixed pitch propellers. You are welcome to participate in both JIP initiatives.
