We’re used to seeing flow fields represented in colour in computational fluid dynamics (CFD), but wheel brand Swiss Side has developed a new aero measurement system that enables real-world aerodynamic drag to also be viewed in full colour, allowing engineers to see where drag is coming from and with what intensity in the wind tunnel as well as on the computer screen. According to the company’s CEO Jean-Paul Ballard, “it literally doubles our measurement capability in the wind tunnel.”
