energy sources from char combustion

onlylno · January 31, 2017, 07:27

Hi everyone,

I am writing a UDF code about the char combustion. I assume the reaction is 2C+O2=2CO. According to theory manual, all energy will be absorbed by particles and not heat was released into gas phase. So is that correct that S->energy += 0 in define_dpm_sources. What about the enthalpy from CO+O2=CO2?
Moreover,
Is it correct that we can calculate yields of product by using the following express: S->species[prod_species_index] += mp_dot/12*28;
mp_dot is the mass loss of char.

Thanks.
