Abstract
The report describes parts of the work performed and some of the work under way during the first halve of 2014. A major part of the work is done within a trilateral cooperation with TNO, The Netherlands and DRDC, Canada. To enhance the predictive capability of a numerical code a better description of cavitation is needed. One possible such model for microcavitation is examined with the aim of implementing the result in a code. A study of the differences from three water models is performed and the results show surprisingly large differences. Most of which can be attributed to losses during compression of water. Additional work under way is, for example, a plan to enhance the experimental facility.
