Flow angle

cfdeng · February 8, 2013, 14:35

Hi,

I want to find flow angle distribution along the span after a rotor blade. which function in CFX-Post should I use to find an average of flow angle for each spanwise position?

Any help is appreciated.

Once you have defined what flow angle actually is then you can plot it in CFD-Post. Are you talking about the flow angle along the chord centre line? Top or bottom face? Or the average flow angle at that chord?

If what you want to see is how the flow is after leaving the blade, you can draw a line right after the blade (along its trailing edge), and then choose to plot a streamline which starts from this line.
Not sure about finding a specific angle, but I'm not really sure of your question either
