Partikel Combustion

Simon Steinmeyer

Hi everyone,

I would like to simualte a combustion of wood partikels: There are two fractions, the char fraction (20%) and the volatile fraction (80 %).

In the fluent tutorial, I only can find an example where I can declare the C,H,O,N-mass fraction. But I want to declare chemical reactions on molecular level.

But this is only possible when I change the "Species Model" from "Non-premixed combustion" to "Species transport" (Volumetric). But in that case, I can't declare a devolatilizing mixture in the injection panel, only one single species. The same problem occurs with the "Oxidizing species" and "Product Species" - there will be more than one product, too.

Any suggestions ?
