Hi fellows,

I'm having the hardest time to simulate a turbulent separation bubble induced by a combination of adverse to favourable pressure gradients.

Some of the experimental data known that could help to carry out the unsteady simulation are: two Strouhal number based on bubble length (separation to reattachment point) and reference velocity, Uref = 25 m/s. The first Strouhal number describes the breathing motion of the bubble, St = 0.01 and the second one describes the emission of coherent structures in (by?) the shear layer, St = 0.35.

Could anyone please give me a hint on how to get to see, for example, u' x t??? Of course I need to first find out the appropriate timestep and total time for the unsteady simulation.

Thanks in advance!
