Erosion on ship propellers and rudders - the influence of cavitation on material damages (EROCAV)

Objective

Cavitations in fluids can cause erosion resulting in severe material damages of propellers and rudders. This may lead to loss of efficiency and even in a total loss of propeller blades. Erosion induced by cavitations can be predicted only by using engineering methods, because the physical process behind is only partly understood. Therefore a scientifically based method to predict erosion induced by cavitations is needed. The main aim of the work is to develop a practical tool to assess the risk of erosion on ship propellers and rudders. Prediction methods (the experimental and theoretical ones) that allow a quantitative full-scale erosion prediction shall be developed. The deliverables will be tested experimental methods and an analytical code to predict cavitations induced erosion. Design guidelines to minimize the risk shall be developed.
