setup ejector unit in helyx os
 

Hello everyone,

As my nick says I am an openfoam beginner:). My first problem is how to setup ejector unit in helyx os correctly, here is the picture from the "air".

I made for main Inlet total pressure (for example for 8bar, 801325/1.205=665000 m2/s2) and for the rest total pressure 0 and velocity type for all input pressure inlet outlet velocity, turbulence model - k- omega SST. Then I made analysis but the result are about (1/5)-(1/10) of real results. Any suggestions?
