KamilSobczak is on a distinguished road
I have three questions:

If I define 3 phases:
- 1st for species transport (chemkin format)
- 2nd for liquid water (coolant)
- 3rd for water vapour (evaporation-condensation interaction between phases).
1. Can I omit drag and slip interaction?
2. How to define compressibility of water vapour? Is the density UDF for compressible liquid flow(udf guide) appropriate for such case? What is BMODULUS?
3. Is spark model unavailable for ignition? Only patch of hot region could ignite this?

Thanks in advance
