An axisymmetric non-hydrostatic model for double-diffusive water systems

The three-dimensional (3-D) modelling of water systems involving double-diffusive processes is challenging due to the large computation times required to solve the flow and transport of constituents. In systems that approach axisymmetry around a central location, computation times can be reduced by applying a quasi 3-D axisymmetric model setup....

Efficient and accurate PLIC-VOF techniques for numerical simulations of free surface water waves

In this paper the attention is focused on the effect of various VOF methods on efficient and accurate simulation of free surface water waves. For this purpose, we will compare several VOF methods in numerical simulations of propagating waves where strong nonlinear behavior is dominant in the flow. Comparisons and discussions will be provided to...

Wave Generation, Propagation and Absorption in CFD Simulations of Free Surface Flows

The PhD study focused on two topics. The first topic was energy dissipation in wave propagation. The wave dissipation can be caused by physical and/or numerical phenomena, such as the free surface treatment, physical viscosity and artificial viscosity due to discretization of the momentum equations. Among these the free surface treatment is an...
