Thermal contributions to aero

[gcdugas]

It should be simple to implement a hot surface into a CFD model. Even though the results may not be true to life, if there is trend it can be seen.

but all in all my input is that at the high speeds where the aerodynamic surfaces on the car start to operate, the mass flow of air is so high over these surfaces, that a moving car will not be as hot as that image posted of the car in the pits and also because of the low thermal conductivity, this huge mass flow of air will barely change temperature.

( i may be wrong )

Well I know there is considerable heat in the wake of an F1 car. Enough that a car cannot follow for too long a period or the following car's cooling will be affected adversely. And I would think that the thermal conductivity is considerable coming out of the chimneys and gills exiting the radiators. And then there is the exhaust plume disturbance issue which I haven't seen addressed yet.

That is mainly because radiators receive turbulent air and overall volume of air passing thru the radiators in a given time reduces significantly.
And air thermal conductivity is indeed low. That is why fur works=)

And don't be fooled, I know they still use those "old school" smoke wands to visually see things in the tunnels too.

At least they don't use older-school pieces wool.
