Advanced Lagrangian Approaches to Cavitation Modelling in Marine Applicationsons. Traditional Eulerian cavitation models compute the vapor content based on computationally efficient, semi-empirical mass-transfer models for cavitation. In conjunction with Lagrangian cavitation models, separate equations for the bubble size and momentum are solved for each individual bubble/nu

Viscous-Flow Calculations for Model and Full-Scale Current Loads on Typical Offshore Structuresn 5 orders is achieved. The sensitivity to grid resolution has been investigated for both model and full scale using five consecutively refined grids and for 3 current headings. The differences in the solution between two consecutive refinements converge for all cases. The numerical uncertainties ar

Viscous-Flow Calculations for KVLCC2 in Deep and Shallow Water dependent form factors. Comparisons with resistance measurements and with an empirical formula given by Millward show good agreement for deep as well as for shallow water depths. The CFD results give insight into the forces and moments acting on the ship as a function of the drift angle, yaw rate a

Numerical Prediction of Erosive Collapse Events in Unsteady Compressible Cavitating Flowsare modeled by closed form equations of state..To assess this novel approach we simulate an experimentally investigated nozzle-target flow. A comparison of numerically predicted collapse events with the experimentally observed areas of cavitation erosion substantiates the proposed methodology. The o

Advanced Lagrangian Approaches to Cavitation Modelling in Marine Applicationsdels as well as its insensitivity to water-quality aspects. On the contrary, Lagrangian cavitation models return an improved accuracy and capture the influence of water quality. Results of an open-water propeller flow investigation confirm these findings and display a fair predictive agreement in co
