“…This is consistent with earlier research [11] and hints at the importance of fluid properties, notably viscosity, not included within the BEM formulation. This is a shortcoming of the BEM and is in contrast to other models, such as the volume of fluid (VoF) [25] and smoothed particle hydrodynamics (SPH) [26,27], which can simulate these viscous effects. However, even in these cases the discrepancy is not perhaps as large as might have been anticipated; the BEM formulation providing an effective upperbound for engineering design/analysis.…”

“…At the department of mathematics at UiO, investigation of runup of nonlinear waves have been studied for decades (Gjevik and Pedersen (1981), Jensen et al (2003) and Pedersen et al (2013)). To investigate the runup of solitary waves, a vareity of different numerical models are utilized, Boussinesq (Pedersen and Gjevik, 1983), Navier-Stokes solver (FLUENT) (Wood et al, 2003) and Boundary Integral Model (Pedersen et al, 2013). Discrepancies between the models and experiments are reported, especially for measurements in the last stages of runup, where capillary and viscous effects are prominent (Pedersen et al, 2013).…”

This thesis is submitted in the partial fulfillment of the requirements for the degree of philosopiae doctor (Ph.D.), at the University of Oslo. The research presented in this thesis is conducted under the supervision of Professor Atle Jensen, Dr. Jostein Kolaas and Associate Professor Johan Kristian Sveen. The work is carried out at the Department of Mathematics, and concerns experimental study of breaking waves. The experiments are carried out in the hydrodynamic laboratory at UiO. The thesis is a collection of four papers and one report. The introduction describes the motivation of the present study, and relates the papers together. The main body of the thesis consists of four journal papers and a report, in chronological order. I am first author on all papers, and was involved in all processes of the research. The research was done as part of the research project DOMT-developments in optical measurement techniques funded by The Research Council of Norway (project number 231491).

“…With the application of moving boundary wave-maker, the motion of a realistic wave-maker (flap-type wave-maker or pistontype wave-maker) is numerically simulated by a moving boundary. For example, Wood et al [10] analyzed the runup of steep nonbreaking waves using the piston-type wavemaker based on the FLUENT software, and Finnegan and Goggins [11] simulated the linear water waves and wavestructure interactions using the flap-type wave-maker based on the Ansys CFX commercial software. Since the computational domain changes as the solid body moves toward or away from the fluid, a remeshing is inevitable in each time step or after a large distortion of the generated grid, which should be avoided as suggested by most researchers.…”

Nowadays, as the development of Computational Fluid Dynamics (CFD) and the numerical wave tank (NWT) has advanced, numerical analysis has become increasingly useful and powerful for the ship designing and ship hydrodynamics. In this study, a momentum source wave-maker and an analytical relaxation wave absorber were embedded into 2D RANS equation model with RSM turbulence closure scheme to establish the NWT for ship designing and hydrodynamics. The VOF (volume-of-fluid) method was applied to accurately capture the water free surface. The body force-weighted scheme is chosen for pressure interpolation and the second order upwind scheme for discretization of the momentum equation. In order to calculate convection and diffusion fluxes through the control volume faces, PISO algorithm is adopted for pressure-velocity coupling. The momentum source function for wave generation and the analytical relaxation function for wave absorption were deduced for constructing the NWT (numerical wave tank). The proposed NWT was then validated by the laboratory measurements of Umeyama and the analytical solution, indicating that the constructed NWT is effective and accurate.
