In the America’s Cup, for example, the design of the sophisticated foiled-catamarans used today in competition is performed almost entirely via CFD. However, CFD is usually performed along with physical testing to get the deepest understanding possible of the flow and because there are sometimes approximations in the CFD models that cannot be avoided, but there are examples where simulations have almost replaced the experiments. You can think of it as a virtual wind tunnel or a virtual towing tank, where designs’ output from CAD software can be tested straight in the CFD software without the need for building the physical prototypes. It’s a technology where the interaction of an object with fluids, like air or water, can be analyzed in a computer thanks to software designed to solve the equations of fluids’ motion, known as the Navier-Stokes equations. Don’t like it.” Not very effective.īut now, thanks to the wave pool revolution, CFD jockeys like Riccardo and his company Red Fluid Dynamics can map out design performances and then test their designs in a stable environment.ĬFD stands for Computational Fluid Dynamics. And then either confirming “oh, yeah mate this board goes unreal” or “nah. ![]() These digital tests could then only be supported by a team rider sessioning a new design in a variety of ocean conditions. It showed only what should work in theory. Modeling of surfboard performance via computer fluid dynamics was previously limited. ![]() ![]() The 42- year-old from Rimini Italy is spearheading the movement to apply computational fluid dynamics simulations to surfboard and fin designs. Well, at least one has.Įnter Riccardo Rossi. The scientists best known for studying airflow and resistance on rockets, Formula 1 cars and various aircraft, have now turned their attention to surfing. That foam and fiberglass sled beneath your feet, including the fins, just got a whole lot of help from the pocket-protector set.
