Abstract

The storage is intended for projects working with simulation of cavitation nuisance at Chalmers, M2/MT. This relates to research on development of computational models for cavitating flows and erosion, and analysis of the incurred nuisance. For the coming year, a new project on predicting cavitation noise related to marine propulsion systems has started. This will involve simulation of a ship in operation in several conditions and analyse and propose methods to assess underwater radiated noise. This requires simulating detailed transient development of cavitation on the propeller blade during operation is needed to analyse the nuisance, thus the simulations are rather demanding both in terms of computational resources and storage. Further, activities related to prediction of cavitation erosion in dual fuel injectors continue. New studies have been initiated on realistic injector geometries to be analysed in relevant operating conditions.
