ahmadijaz is on a distinguished road

I am trying to simulate combustion of Unsymmetrical dimethylhydrazine (UDMH -C2H8N2) and Nitrogen Tetraoxide (NTO-N2O4). UDMH is in liquid form and NTO in gaseous form. Combustion reaction is;


I am using DPM for UDMH evaporation and non-premixed combustion model for complete analysis. I have manually added UDMH polynomial coefficient in thermo.db file and liquid UDMH properties in propdb.scm.

I want to ask that, is it necessary for the compound to be present in vapor form also in propdb.scm file? Because with every single tutorial I came across involving DPM like n-pentane combustion analysis (present in the fluent tutorial guide), n-pentane (C5H12) in PDF mixture showing the properties of n-pentane-vapor present in propdb.scm and in droplet mixture n-pentane is showing properties of n-pentane-liquid also present in propdb.scm.

Please help me in this i ll be very grateful.
