Boundary Conditions for flow over a hot road (sprayFoam)
 

Hey,

I'm trying to set up a case with a gas mixture moving over a road. The flow velocity should be 0.1 m/s, the lower boundary should be a hot road (at 50°C). The rest of the patches is meant to be "atmospheric", i.e. i don't want any interaction with the flow. I tried it using zeroGradient for those patches.
I'd be happy if anyone had a second to tell which BC are adequate for my case. U, p and T are sufficient, k and epsilon would make my day.

Thanks!

Rob
