Hi there,

I am masters student, i am working on Coal Gasification. Need not to say very much new to fluent. I wish to study mass transfer when reactant gas (H2O) passed over coal seam. Can any one suggest which model should i use, well, i am not sure whether Multiphase model or descrete phase (Or even Porous media) model will work.

i will be greatful if anyone could reccomend model to me. with regards ,

yes! as i am trying to study only effect of pressure on gasification rate on coal seam. So i am assuming only Steam is passing over seam. well, practically it wont be an ideal case.

Multiphase is an good option, but i am not sure how to introduce detailed reaction mechanism (surface and gas phase reactions). well, you can get useful info from this forum as few good people are around in this forum.
