Hello,

I have some problems like in topic with mixing 2 fluids: water and oil. I wanted to show how oil is flowing through the channel with baffels and "mixing" with water. I had some questions:

1. Which model of mixing fluids i should use:
VOF is to immiscible fluids.
Eulerian: I got very odd results.
and I used Mixture and I have some problems with it. Everyting works ok. Velocity, pressure and temperature spread out ok but when I checked denisty is not ok. It looks like oil stopped in channel and only water flow further. I will show what I am writing about.

Density of oil: 889 water 998.2
Velocity inlet1 and inlet 2: 1 m/s
Temperature of water 350 K and 280 K oil

I'm counting on Your help.
