Ship sinkage and trim predictions based on a CAD interfaced fully nonlinear potential model

We present the results of a model for ship fluid-structure interaction simulations based upon the potential flow theory. The govering Laplace equation is complemented by non penetration boundary conditions on the boat surface and by fully nonlinear kinematic and dynamic water free surface conditions, written in semi-Lagrangian form. The hull is represented as a three dimensional rigid body subjected to the action of gravity and hydrodynamic forces. The spatial discretization of the fluid dyna...

Model order reduction by means of active subspaces and dynamic mode decomposition for parametric hull shape design hydrodynamics

We present the results of the application of a parameter space reduction methodology based on active subspaces (AS) to the hull hydrodynamic design problem. Several parametric deformations of an initial hull shape are considered to assess the influence of the shape parameters on the hull wave resistance. Such problem is relevant at the preliminary stages of the ship design, when several flow simulations are carried out by the engineers to establish a certain sensibility with respect to the pa...

Multi-physics modelling and sensitivity analysis of olympic rowing boat dynamics

A multidisciplinary approach is implemented to model and analyse the performance of Olympic rowing boats. A reduced-order model that couples rowers motions with the hull, oars and hydrodynamic and hydrostatic forces is detailed. This model is complemented with a sensitivity analysis carried out by means of a non-intrusive polynomial chaos expansion. Sensitivity analysis results for two different boat classes, namely, a lightweight single scull and a coxless four are presented and discussed. T...

Fluid-structure interaction problems in free surface flows: Application to boat dynamics

n this paper, we present some recent studies on fluid–structure interaction problems in the presence of free surface flow. We consider the dynamics of boats simulated as rigid bodies. Several hydrodynamic models are presented, ranging from full Reynolds averaged Navier–Stokes equations to reduced models based on potential flow theory.

An efficient shape parametrisation by free-form deformation enhanced by active subspace for hull hydrodynamic ship design problems in open source environment

In this contribution, we present the results of the application of a parameter space reduction methodology based on active subspaces property to the hull hydrodynamic design problem. In the framework of such typical naval architecture problem, several parametric deformations of an initial hull shape are considered to assess the influence of the shape parameters considered on the hull total drag. The hull resistance, which is the performance parameter associated with each parametric hull, is t...
