Dear all,

i'm simulating wood logs combustion in fixed bed. I treated the whole wood logs as porous media and apply the non-premixed combustion.

all researched paper seem to model the wood particle, wood chip, dust but not the wood log as what i'm doing now.

i just wondering whther i'm doing the right thing or not?

any advice/

thanks in advance

you are not doing the right thing, you should use multiphase: solids, organic oils released at fast pyrolisis and gas
