Creating an accurate model of wind and wave behavior has long challenged sailors and naval architects. The problem’s always been the niggling gap between mathematical calculations and physical tests. But science now has a way of closing that margin that could revolutionize sailing with a simulation said to behave as accurately as real-world tests.
Ignazio Maria Viola, head of the the Yacht and Superyacht Research Group at Newcastle University, set out to simulate how water and air behave around a boat in different sea and wind conditions. The goal was to predict how a yacht will behave during a particular race under particular circumstances. He worked with the Yacht Research Unit of the University of Auckland and the Italian supercomputer center CILEA to develop a virtual test he says matches physical trials. The models could save race teams money and help them prepare more thoroughly for events like the Volvo Ocean Race or America’s Cup by modeling different boats in different conditions.
“We believe that today we are experiencing an overturning of the traditional hierarchy between physical and numerical experiments, which will become more and more dramatic in the future years,” Viola said.
