Resistance & Propulsion

MARITIME RESEARCH PROGRAMME

We aim to improve the prediction and evaluation of the resistance, propulsion and cavitation hindrance of ships in order to get better ships and blue oceans.

sub programmes

PROPULSION PREDICTION

This sub programme focusses on improving specific aspects of model tests such as powering prediction in shallow water and at low Reynolds number. Validating CFD predictions is continuously ongoing following improvements in e.g. a model to account for roughness. The understanding of propulsor performance is enhanced by the development of an energy loss analysis of CFD computations.

Cavitation Hindrance

This sub programme focusses on improving specific aspects of predicting cavitation hindrance such as the inception of cavitation in model tests, predicting and full-scale measuring of hull-pressure fluctuations and underwater radiated noise, and predicting cavitation erosion.
Specific two-phase flow aspects such as propeller ventilation and improving the prediction of the effect of air lubrication on hull resistance are also considered.
