ETAB model in CFX

alastormoody11 · June 17, 2010, 07:33

Hi,
I am using the ETAB model so as to model the secondary spray breakup, in CFX as also particle tracking for a spray simulation and since both of these are accurate only when the volume fraction of the liquid droplets is low is it advisable to have a very fine mesh at the injection point?

Regards,
Ashish

No, the opposite. It is advisable to have larger elements so as to increase the amount of gas relatively to liquid.
