Fluidised bed gasification
 

Anybody can give me an idea for modeling two phase flow (particle and gas phase) in a fluidised bed gasifier.

My interest is to actually visualise the bubbling of the particle phase (different particle sizes) in a fluidised bed gasifier. Firstly, is it possible to visualize the bubbling of particles in the post processor? Secondly i would like to visualize the mass gradience of the different size of bubbling particles (4mm-10 microns) in the gasifier.

Any literature is available on the same? What are all the models to be incorporated?
