Description
Linear and non-linear hydrodynamic coefficients of single and multiple hulls are
obtained using the boundary-integral method. For linear frequency-domain analysis, the
boundary-integral method based on a simple source distribution (Yeung [50] was used.
The nonlinear time domain simulations were carried out using a boundary-integral
algorithm based on the mixed Eulerian-Lagrangian (MEL) formulation (Longuet-Higgins
and Cokelet (19] ). Also, linear time domain simulations were carried out by utilizing a
simplified mixed Eulerian-Lagrangian formulation and the steady-state results compared
with that obtained from linear-frequency domain analysis. Both 2D and 3D results were
obtained for a range of parameters such as beam/draft, hull-separation/beam ratios and
frequency and amplitude of hull motions. The results shed light on complex wave-body
interactions involved in multi-hull ships and identifY critical hydrodynamic and
geometric parameters affecting their sea keeping performance. The computational tools
developed and the findings thus contribute to design of multi-hull ships for improved atsea
performance.
