Default Low Speed flow in Micro Gravity; what model?
Posts: n/a
I am modeling the airlfow in a Rack Volume on the International Space Station using Fluent. What Viscous model (ke, kw,...) would be most accurate for that kind of flow? The maximum airspeed is right around .5 m/s and that is only in a few localized areas. Average speed is right around 5cm/s. I have been using the kw model but I am not so certain that is the best choice -- no real reason for my scepticism though... Any wisdom would be appreciated! Brice
