Coal gasification

      Hello everyone


      I am using licensed version of Ansys fluent 14.1


      I am simulating biomass gasification in Euler-Euler method with sand as bed material i have defined input velocity of air and biomass 


      In boundary conditions i am confused  how to define mas species for the reaction. I know the proximate analysis of the biomass 


      I also want to know can i solve this without writing user define functions  as i can use built in single rate kinetic model

      Hell Manu, 


      I am not expert, you may want to look at following video.

      Hi

      How can i model devolatilization of biomass/coal using eulerian-eulerian approach? Do i have to use UDF?


       


      please guide

      Hi,


      For the OP. I'm not sure for R14 but if you can upgrade to the R19.x version there are a lot more tools and functions in the multiphase solver. You'll also see significant speed and stability improvements. 


      Maliuzair: You can model devolatilization using the E-E approach (it may not be easy, you may need UDFs and you will need species models), but DPM may also be suitable: check the guides for suitability.  I can't be more specific as unfortunately this question is the beyond the scope for ANSYS employees to answer on a public forum, so hopefully other student community users can chime in.


      Cheers,
      Rob
