outflow BC for multiphase system
 

Hi, I have a multiphase system with one intet and two outlets (OUTLET-1 and OUTLET-2).

I want to specify that the 15% of the volume flow rate exits from OUTLET-1 and the remaining 85% exits from OUTLET-2.

What type of boundary conditions should I use? I do not know the pressue before hand. FLUENT manual says that the outflow (mass spilit) BC can not be used with multiphase flows.

Please suggest,

Thanks, Kushagra
