Three phase problem in Trickle bed
 

Hi,

I've tried to model a Trickle Bed reactor by both options 1) Three phase eulerian 2) 2 phase eulerian with porous media. Both simulations had convergence problem.

Problem for Gas & liquid phase is how to define the bubble dia considering gas is continuous phase.

For the 3 phase case, I patched solid vol fraction i.e. (1 - bed voidage ) in the solution domain, but to my surprise, solid volume fraction keeps on changing and eventually get replaced by the liquid & gas which is not correct.

Anybody has any clue?

Response will be appreciated.
