Propeller nozzle for ships Steerprop Ltd

Using the latest CFD-methods, parameters were found, that enables a significant improvement in bollard pull and at the same time reducing the nozzle resistance at free running speeds.
The solution was found by designing the interior surface of the nozzle for maximum bollard pull, whereas the exterior surface was optimized for high free running efficiency. The nozzle design optimization was performed for the complete propulsor, i.e. including also the underwater part of the propulsion unit itself.
