Inflow Angle Computation

Up to Using openWind

Inflow Angle Computation

Posted by Matt Gagne at June 15. 2010
Hi, Nick,

Can you give any details on how the inflow angles are calculated?

I've only found them when you calculate a wind map from tab files. Is there any way to get inflow angles from a resource grid?

Cheers,

You can right-click on a terrain raster and ask openWind to calculate them from terrain steepness but I really REALLY don't recommend it. You're best bet is to use software like Meteodyn WT or you could use openWind's wind flow model just to produce the inflow angle layer and then use that with a wind resource grid from WAsP or whichever wind flow software you're using. It is OK to use different models for what they do best and then combine the results. I would trust the wind-flow model in openWind to calculate inflow angles much more than I would trust it to come up with accurate wind speeds.
