Towards convective cell free surface modelling of a SPAR buoy

Towards convective cell free surface modelling of a SPAR buoy
Towards convective cell free surface modelling of a SPAR buoy

The focus of this work is the development of a finite volume Euler scheme aimed at the solution of three dimensional unsteady free surface hydrodynamic problems. Excessive mesh distortions due to surface movement are avoided by monitoring both geometrical and flow properties and adapting inadequate geometric entities. The free surface is defined by bi-cubic patches, joined to the flow solver by nodes of the computational mesh at the surface. Surface definition and tracking is gained from the parametric coefficients of these patches. The flow around a truncated cylinder is presented as a case study of the work achieved so far.

Abstract

The focus of this work is the development of a finite volume Euler scheme aimed at the solution of three dimensional unsteady free surface hydrodynamic problems. Excessive mesh distortions due to surface movement are avoided by monitoring both geometrical and flow properties and adapting inadequate geometric entities. The free surface is defined by bi-cubic patches, joined to the flow solver by nodes of the computational mesh at the surface. Surface definition and tracking is gained from the parametric coefficients of these patches. The flow around a truncated cylinder is presented as a case study of the work achieved so far.
