F1 Evaluating ‘Wheel Arches’

Here are our CFD links and discussions about aerodynamics, suspension, driver safety and tyres. Please stick to F1 on this forum.

... It happens on road cars too and their tyres are cold, especially in wet weather.
... not enough to cause significant enough evaporation to create a dry line behind the car. The vastly more significant way that standing water is removed from the track is physically moving it with the tyre...
road or track the tyres of each speeding car are a 100+ kW 'hair dryer' acting on one part of the road surface
'drying' ie reducing in various ways the suspended liquid water aka spray by heating the 'physically moved' water
ie the notional moving effect doesn't occur without the effects of that heat occurring

plus F1 wheel aerodynamic drag will also heat local air (maybe 50 kW) - and heat it by brake cooling (maybe 200 kW)

all the above mechanisms present as 'standing water physically moved with the tyre'

What's your point? Yes the tires heat up, but also it's irrelevant. The massive amounts.of water soak up the heat easily. Water is also one of the highest heat capacity substances known.
