Help on Rogallo's procedure??

nikz123 · June 1, 2016, 07:13

Hello CFD users,

I am starting to simulate decaying homogeneous isotropic turbulence in a periodic cube.

After looking at many procedures in almost every papers people address about Rogallo's procedure for generating the initial velocity field which is divergence free for incompressible flows.

Can anybody please explain on how Rogallo's procedure is carried out for this type of simulation study. It will be of great help!!

Thank you

Hi,nikz123 I do the similar work with you, and i used profile to simulate the boundary. but i think the results is not proper.
