Default Combustion expert?
Posts: n/a
I'm modelling a solid fuel (lignite) combustion in a 3d furnace (non premixed combustion). For the fuel, one empirical stream will be used in prePDF (CHONS concentrations are known). How can I include the fuel moisture? Do I consider of it when I define the injections (If yes, where?)? (Wetcombustion page is not available under my current settings, although H2O(L) is included in the species in prePDF).

I have read the "Non premixed combustion" and "Discrete Phase" user guides and the corresponding tutorials, and I understood everything else, except for this. Is there something that I miss?

define it as water in vapor form or as u requires..specify model fraction in prdpdf and calculate the look up table

Thank you for answering my question but how is it possible to include vapor (H2O) concentration when I want to use only one, empirical fuel stream (CHONS fraction definition)? Should I convert the water content to CHONS atom fraction and add the latent heat in material properties panel (for fuel)?
