Hello ,
I'm trying to model NH3-oxy combustion through eddy dissipation model but i m getting too high temperature values. I use one step reaction as NH3+0,75O2 = 0,5N2 + 1,5H2O. I shared the details of my model as follows;
1. Equivalence ratio : 0,83
2. Thermal power: 10 kw
3. Viscous model: k-epsilon
4. Eddy dissipation model
5. mixture materials has been taken from fluent database for nh3 and other species. (i dont know exactly which properties can i change on mixture material to decrease temperature values)
6. Reactions dialog box: rate exponents both for nh3 and o2 are 1 , for products are zero. Mixing rate values A : 4, B: 0.5 ( i have changed the A value from 4 to 1 but no avail)
7. radiation model is P1.

Consequently, what should i do to get plausible temperature values for nh3-oxy combustion. your suggestion will be very helpful .
Thanks in advance.
