the_sixth_hokage is on a distinguished road
Hi..

I'm modelling a trans critical combustion of CH4-LOX..

I was looking for any UDF codes which can be used for cryogenic combustion...the default kinetic theories doesn't seem to work...

Can anyone provide UDF code for mixture viscosity..

vinerm will become famous soon enough
It appears that the requirement is not just the UDF but some physical model that is applicable for your case. As far as UDF is concerned, it would be easy to write provided you have a model for viscosity. For a model, you have to do some study; look through the literature.
