hi everybody,

I am no to this forum and new to Fluent . I have to do an analysis of an solarcollector for a solar thermic power plant. the profile conture has a parabolic shape and this I have to feed in fluent. but the angle of attack is so high (30° from zenith) that the normal steady approach doesn't work. so could you give me some advice how to set up fluent, so that I get out representative values and that the pulsive turbulances can be handled?

I am a real newbie and the first tests doesn't lead to convergence of the residuals and of cd.

thx in advance for any kind of tip!

greets, Andreas

hi again,

btw, I have a gambit modell for the 60° version here http://horn.hdtvtotal.com/download/p...ektp60deg5.zip perhaps that will helpto understand. and yes, the 5km starting distance is needed to get a specific wind profile.

greets, Andreas
