Hi Guys

I am trying to simulate the Hypergolic Rocket fuel (UDMH(l)+N2O4(g)) Combustion using Fluent. I am little confused with the selection of combustion model. ANSYS Fluent Manual says that for liquid non-premixed combustion i should use Non-Premix combustion model. But in research papers authors usually talk about EDC and EBU models for combustion reaction. Kindly see the attached picture.

Right now i am using DPM for UDMH evaporation, Non-Premixed combustion model and k-epsilon model for turbulent modelling for my analysis. But results are not good.

Kindly suggest me which models should be used for this kind of cfd analysis.
