Hello,

I'm trying to model an injection of water to a stream of superheated steam. I'm using VOF Model, with Lee condensation model for the phase interaction. The material properties are set to constant first as i'm still new to this kind of simulation. the turbulence model i used is k-epsilon realizable. For context, here are the design conditions:

Superheated steam inlet:
Pressure: 7.7 Bar abs
Temperature: 5 degree Celcius above saturation temperature (sat. temp. 168.835 deg. C)
mass flow rate: 80 kg/s

This steam is to be lowered to saturated temperature by injecting water at 30degC with injection pressure 1 bar abs above steam pressure. by calculating using heat and mass balance equation, the water flow rate needed is 0.397 kg/s

I use velocity inlet for both the steam inlet and water inlet, and pressure outlet. the scaled residuals fluctuated and wont go down, what can i do?
