what cfd is this?
-
have you done any runs where you've seen asymmetric shedding across the nozzle? just wondering since that startup transient can be a sizable side load. thanks!
-
Hi, have you written some article about this,or can you recomend me some? Thx
-
@byustanfordboy Thank you!!
-
Hey which software you used for the post-processing visualization..
-
SO you're using Finite difference compact schemes with artifical diffusion?
What kind of shock sensor are you using?
Have you considered weno finite difference/central schemes.? THeyre usually faster and well suited for LES. with strong shocks.

Hello,
I'm new at this and as far as I've seen the shocks should be outside the nozzle... We'll maybe I'm getting it all wrong. Could you please comment on this. Thank you in advance!

@phph4v31aye
Internal shock waves are common in nozzles as are external ones. This simulation focuses on the former.

is it 2D or axisymmetric?

@Buddhabr0t
This is 2D calculation, reflected about the center line.
