We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Here you see the comparison of velocity profiles for different grids (grid 1 the coarsest, grid 4 the finest (505,000 cells). These results are achieved with SST including curvature correction on the polyhedral mesh with prismatic layers at the wall (y+ >30). I also noticed that some CFD-users suggest hexahedral mesh over polyhedral mesh for cyclone simulations. 

 

 

With respect to experimental data: 

 

Euler number in experiments is 5.1 [-], whereas my simulations results in roughly 20% higher value of 6.2.
