some results with Kl-kw-w transition model
 
Transition model = K-Kl-omega
Reynolds number = 5e04
Turbulence Intensity = 0.4%
Time step is taken in such a way so that one cycle is modelled in 100 time steps.
Cylinder is modeled as moving zone and purpose of this study is to observe the effects of upstream wakes on boundary layer transition in downstream low pressure turbine rotor profile.

i was testing cfd-post and i made this yesterday: http://youtu.be/ghl6WKlNWnA i don't know about the accuracy of the resultsbut cfd-post is really a powerful tool

How long did it take to create that video? Must be hours, right?

Far June 12, 2013 04:46

Yes. Around 3.3 hours for one cycle.

it took me days for that video... more than 400 time steps, and the mesh is 1.2 million nodes

400 time steps! wow ;)
