Borahel is on a distinguished road
My name is Rafael Borahel.
I'm currently having problems with the modeling of a problem biphasic

My problem is in a microtube with R134A evaporating.
At the entrance of the tube I set the volume fraction as 0.5 vapour and 0.5 liquid. This definition can be seen in the image below.

Red is Vapour and Blue is Liquid

But it's not working.
By changing the orientation of the image, you can see that I'm doing something wrong, because this setting was just right at the entrance and not along the tube. You can see it in the image below.

Red is Vapour and Blue is Liquid

What am I doing wrong?
