Estimation of "inlet solid volume fraction"...?
For circulating fluidized bed, we generally know that the superficial gas velocity (m/s) and solid flux(kg/m2 s). In addtion, the solid and gas densities are also known.
Then, my question is:
How to estimate the "solid volume fraction at the inlet"? As we know,this parameter is needed as input in E-E two-fuild simulation.
Could you please give some ideas and recommend some proper estimation approach?
Re: Estimation of "inlet solid volume fraction"...
There is a method proposed in Gidaspow's book:
Es = Ws/RO_s/(Ug/Eg-Vt)
where Es-- Solid volume fraction
Ws-- solid flux
RO_s --- solid density
Ug--- superficial gas velocity
Eg --- Gas volume fraction
Vt--- terminal velocity
I am not sure whether it is suitable for your system. Hope this helps.
