Numerical and experimental study on coupled hydroelastic behaviour of VLFS and OWC chamber

Abstract

In the present study, an OWC-chamber is introduced at an arbitrary location of VLFS to investigate the influence of the location and shape of OWC chamber on the hydroelastic response of VLFS by model tests and numerical analysis. Three two-dimensional VLFS models with elastic similitude were considered for comparison with numerical results. Model test results were compared with Hong and Kyoung’s1,2 numerical works, in which a finite element method is applied both to fluid domain and structure motion. Comparisons were made between the numerical and experimental results, and reasonably good agreement was obtained. In addition, Hong and Kyoung’s2 numerical work is extended to various combination of OWC and VLFS, and special attention is paid to linking mechanism between OWC chamber and VLFS.
