Default eddy dissipation model: combustion doesn't occur

roukaia is on a distinguished road
i am working on 2D combustion chamber i achieved the cold flow and now i am working on combustion i used eddy dissipation model to model combustion
I set up a model by
- activating energy equation
- Enabling the Standard K-E model
- Enabling DPM model
- Enabling species and transport reactions model with eddy dissipation model activated in particle/volumetric reactions.

but the rate reaction still 0 even with mass fraction of co2 and h2o =0
i use k epsilon for turblent model and group injection for diesel C10h22
my conditions boundary are pressure inlet -oulet
please does anyone have an idea why the combustion doesn't occur with eddy dissipation moI want to initiate the combustion in my model, but its not working.

Did you set the DPM particles as evaporating? they wont burn as liquid, you know

Edit: this is necro posting xD
