Computational Fluid Dynamics

Steady / unsteady aerodynamics

Using state of the art numerical simulations, A2V is able to accurately predict the aerodynamic behavior
of complex shapes, in both steady and unsteady conditions.

High speed hull resistance prediction

The simulation of high speed stepped planing hulls is solved by means
of RANSE-VOF software in order to get accurate prediction of hull resistance.


High speed seakeeping

The dynamic response in seaway of our boats,
is predicted thanks to a strong coupling of the RANSE code with our
in-house aerodynamic model.


Surface piercing propeller

The challenging numerical simulation of surface piercing propellers is currently under development
in order to improve our understanding of this promising propulsion system and its interaction with the boat’s behavior.


Mathematical modeling

Unsteady aerodynamics of wing in ground-effect

Using intensive systematic CFD simulations, the A2V team has developed a fully unsteady
aerodynamic model for wing in ground effect.


Hydrodynamic model of stepped planing hulls

Our in house semi-empirical hydrodynamic model for stepped hulls solves the hydrodynamic behavior in both frequency and time domain.
The wake of the forebody is taken into account to solve the aftbody response.


Seakeeping simulator

Our 2 DOF seakeeping simulator couples the semi-empirical
hydrodynamic model with the aerodynamic model.



A user-friendly manoeuvering simulator is able to simulate boat-landing approaches
and low speed manoeuvers in general. It can be implemented in virtual reality simulators for training purposes.


Naval architecture

Hull shape design

The A2V knowledge in naval architecture allows us to develop innovative hull shapes
in order to increase fuel efficiency and comfort at high speed.

Aerodynamic design

Detailed aerodynamic design is the key to maximize the aerodynamic alleviation efficiency.
