Hello,
I would like to study the flow of air in a rotating turbine. The goal is to create an air flow from the bottom by rotating the turbine at 15.000 rad/s.
I am using Floworks 2009 for the first time for this project.
So, before working on the real turbine model I made several tests on a very simple form of the turbine in order to choose the best way to simulate it, since there are different ways to add a rotation on a model.
So far, I could see that there are 6 different ways of modelisation:
Using a Global Rotation, a Rotating Region or Moving Walls with an Internal or an External analysis.
There are many differences among the results, depending of the method used. Which one would you think is the best to simulate our case, considering that the rotating speed is around 15.000 rad/s ?
You can find joined the screens I made for each method, with some explanations about my choices (all the examples following were made with a -20 rad/s rotating speed).
Thank you for replying.
