Species Transport with Multiphase flow in FBR
 
Hi everyone,

I have a problem where i need to simulate a fluidized bed where the bed material or the solid phase is sand and the Gas phase is ( Oxygen and Nitrogen) both have velocities 0.3 m/s currently iam using the Eulerian model for multiphase and the species transport for the two inlet gases....

could anyone kindly let me know how to club both multiphase and species transport models ( as both of them have phase one and phase two respectively) where in species model it could be two species but in multiphase its two phases...

so the problem here is i could not define the material properties for the two phases of which phase one consists of two gases with respective velocities and phase two is sand......

Thanx a lot in advance

define o2+n2 as a mixture. when you define the two phases, the primary phase will be the gas mixture and the second phase will be the solid particles.
