I Stokes Number for Particle Motion?

  1. Oct 26, 2016 #1
    I have a question... With the Stokes Number you can derive if particles follow a streamline or not, right? Lets say I am in a windtunnel, the wind is coming from the east. And I have a tube in the wind tunnel (horizontally located) which is 180° opposite to the flow (the opening of the tube is located to the west), and which sucks air with a known flow into the tube. Now I wanna know which particles (which diameter) will follow the streamlines to get inside the tube.
    In principal, the Stokes Number would be appropriate... But i does not consider the flow inside the tube and the bend streamlines. So I am kind of helpless right now.

    Thanks for any hints :)
