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 analysis of the incurred nuisance related primarily to erosion and noise. For the coming year, the project on predicting cavitation noise related to marine propulsion systems will expand from the current one PhD project to an additional PhD project and a post-doc project. This will include analysis for a complete ship in in several operating conditions and variations in the propulsion system. This will further involve specialised studies canonical cases to new methods in to predict noise propagation. All thes requires simulating detailed transient development of cavitation, thus the simulations are rather demanding both in terms of computational resources and storage. The activities related to prediction of cavitation erosion shifted last year to issues with water jet propulsion systems. This project will end during the year as the PhD defence is planned to be performed before the summer. During the spring it will however require storage resources. A new project on cavitation modelling will be started during the spring. Storage requirement can be expected to be limited during the spring but picking up towards the end of the year.
