An Experimental Study on Maneuvering Hydrodynamic Forces in Shallow Water

概要

論文の詳細を見る
This paper presents experimental results on the maneuvering hydrodynamic forces in shallow water with some theoretical considerations. Force measurement tests by means of a PMM were performed with use of three kinds of ship models at various water depths. The experimental results show general features of the shallow water effects on the maneuvering hydrodynamic forces including hull forces and rudder forces. Theoretical studies were also made to examine the shallow water effects on the hydrodynamic derivatives of hull and on the hydrodynamic interaction between hull and rudder. Furthermore, with aid of theoretical studies, practical formulae for estimating the linear hydrodynamic derivatives in shallow water were developed.
