AB Cavitation is a major concern in naval craft design as well as in the shipping industry. Although the nature of cavitation is not fully understood, propeller
designs are presently improved by experimental analysis of the phenomena. Enhanced methods for the simulation of cavitating flow will become useful in design as well as in the efforts to characterise and understand cavitation.

The thesis concerns simulation of cavitating flow using an incompressible solver employing a single continuum volume fraction approach for free surface capturing.
Given the transient nature of cavitation and the flow problems targeted by the model, turbulence modelling is approached using Large Eddy Simulation, LES.

The thesis concludes that the underlying method for modelling unsteady flow and
in particular turbulence is of utmost importance to successful cavitation
modelling, and due to resolution requirements demanded by the cavitation physics itself, LES is presented as a natural choice. A substantial part of the
thesis is therefore dedicated to the evaluation of available LES methods and their application to marine flow problems.
