can FLUENT simulate segregated flow? if yes, what is the model i should use? VOF or ASM?

if my pipe is a hilly terrain configuration, what value do i have to patch on the volume fraction and do i patch the whole pipe? does the value of volume fraction calculated from superficial air and liquid velocities? does it the formula of volume fraction=Vsl/(Vsl+Vsg)? pls give any advise. thanks

U should patch the initial volume fraction (before the fluid starts moving), fluent will look after the time evolution.
