A 2D+T VOF fully coupled formulation for the calculation of breaking free-surface flow
TLDR
In this article, a finite-volume method adapted to a structured or unstructured mesh is used to solve the Navier-Stokes equations and the free surface is simulated by the "volume-of-fluid" interface capturing method.Abstract:
We present the results of simulations obtained with a free-surface flow solver based on the following method. The free surface is simulated by the “volume-of-fluid” interface capturing method. This code solves the Navier–Stokes equations using a finite-volume method adapted to a structured or unstructured mesh. The system is constructed using a fully coupled approach. This global approach allows the simulation of complex flow as a breaking or merging wave. Moreover, with the use of a 2D+T decomposition, it is possible to simulate three-dimensional steady flow.read more
