Hydrodynamic analysis of a floating vertical cylinder
Hydrodynamic analysis of a floating vertical cylinder
The pitch free decay test response of a floating vertical cylinder will be studied throughout this paper.
The present case is based on an experiment (Paredes et al., 2015) and subject of different CFD validation studies (Palm et al.,2015, Rivera-Arreba et al, 2017). Both have found significant discrepancies regarding the damping and natural period of the system for the pitch motion. The purposed test case will be verified
and validated with the CFD solver ReFRESCO based on a cell-centered finite-volume discretisation with unstructured grids. The fully unstructured hexahedral grid generator commercial package NUMECA Hexpress will be used. Furthermore the results will be compared with the experimental investigation performed by (Paredes et al., 2015).

Abstract
The pitch free decay test response of a floating vertical cylinder will be studied throughout this paper.
The present case is based on an experiment (Paredes et al., 2015) and subject of different CFD validation studies (Palm et al.,2015, Rivera-Arreba et al, 2017). Both have found significant discrepancies regarding the damping and natural period of the system for the pitch motion. The purposed test case will be verified
and validated with the CFD solver ReFRESCO based on a cell-centered finite-volume discretisation with unstructured grids. The fully unstructured hexahedral grid generator commercial package NUMECA Hexpress will be used. Furthermore the results will be compared with the experimental investigation performed by (Paredes et al., 2015).
