24.7.2.2.6. Combusting Particles with the Multiple Surface Reaction Model

If the multiple surface reaction model is used with combusting particles, ANSYS Fluent will include additional reporting on the mass of the individual solid species that constitute the particle mass.

(*)- Multiple Surface Reactions -(*)
Fate Species Species Content (kg/s)

---- ------- ---------- ---------- -------
Escaped - Zone 6 c<s> 6.080e-02 1.487e-06 100.00

Escaped - Zone 6 caco3 8.000e-03 5.260e-03 34.25
The total mass of each solid species in the particles at the start and end of the trajectory is reported in the Initial and Final columns, respectively. The percentage of each species that is reacted is reported in the %Conv column. Note that for the solid reaction products (for example, if the mass of a solid species has increased in the particle), the conversion is reported to be 0.

Hi Guys,

Does anyone knows how to decompose CaCO3(s) into CaO(s)+CO2(gas) in fluent ? In user guide there is a title "24.7.2.2.6 " it shows that fluent has a capability of doing calcination or decomposition of calcite.

Can anyone give a simple support ?

Dear ardismo,
Have you found a solution? Can you please give some suggestions?
Thanks
