Hi

I am trying to model an ejector with 2 inlets and one outlet. In the first inlet I have hydrogen with low pressure, in the second inlet I have (hydrogen 30% + steam 70%) with a higher pressure. The material from the second inlet is sucked to the ejector due to pressure gradient. There is no chemical reaction. Two inlets just mix together.
The outlet will be (hydrogen + steam), however I don't know the mass fraction of the species.
The flow is turbulence.

I don't know how to define the compositions of the second inlet as well as the outlet. should I use multiphase flow or...?
I almost tried every thing. I appreciate your help.

Elham

Hi

The problem can be solved by using two physics together:
1- Fluid Flow (single phase, turbulent) 2- Chemical Engineering (Transport of concentrated species)

First, you have to simulate the flow. Then use the solution (flow velocities) as the input for solving the species transport.
