Abstract

Prediction of hydrodynamic forces acting on a ship hull is important to understand the manoeuvring performance of a ship at the initial design stage. To achieve the hydrodynamic forces, CFD calculations that directly solve the Navier-Stokes equation are often used recently, but they require much computational costs. Panel methods can also accurately represent the shape of a body and predict hydrodynamic forces acting on the body. SQCM (Source and Quasi Continuous Vortex Lattice Method) is one of panel methods which was developed at Kyushu University, and it has been confirmed that has a good accuracy to predict hydrodynamic force produced by a propeller. In this study, the SQCM is introduced to predict hydrodynamic forces acting on a Wigley hull in manoeuvring motion. In order to represent flow field around the Wigley hull appropriately, two kinds of free vortex models to be applied to predict hydrodynamic forces acting on the Wigley hull using the SQCM are examined. Predicted results are compared with model test results to verify the effectiveness of the free vortex models. The purpose of this study is to investigate the applicability of the SQCM to the prediction of hydrodynamic forces acting on a Wigley hull.
