Hello
i want to simulate the phase change of freon using ANSYS FLUENT through straight capillary tube


the Dimensions of capillary tube :

inner diameter = 1.5 mm
length = 1500 mm


the objective of this simulation is to plot pressure, velocity and quality distribution along capillary tube
thanks

hi i want to simulate the phase change of freon through capillary tube

1-i wish to use gerber cavitation model in ansys fluent to study phase change

2- how can i define the thermophysical properties as polynomial function of temperature




how can i solve the problem of phase change any advice helps me

hi all
i am want to simulate phase change from liquid to vapor
the liquid is set as a contineous fluid and vapor as a dispersed fluid
i am using thermal phase change
there is no results to me
i appreciate any help in this field thanks

thank you dear
i have small diameter long tube
the working fluid is freon
now let me explain the phenomenon : the freon enters to the tube as a liquid freon and after some distance ,flashing phenomenon will takes place and vapor will form . in this way i have two phase fluid flow
that is mean there is phase change takes place from liquid phase to mixture(liquid + vapor)phase .
i want to simulate this phase change problem
