Complex fluid dynamics may explain hydroplaning – Phys.org

When a vehicle travels over a wet or flooded road, water builds up in front of the tire and generates a lift force. In a phenomenon known as hydroplaning, this force can become large enough to lift the vehicle off the ground.
In Physics of Fluids,, scientists from the CNRS, the University of Lyon, and The Michelin Group use a laser imaging technique to study water flow in front of and through tire grooves.
To counteract hydroplaning, tread designs are chosen to drain water from the front of the…
