Homogenous flow (Taylor & Pettigrew, 2000)

This model assumes no relative velocity between the liquid velocity U1 and the gas velocity Ug . Slip S between the two-phases is:

S = 1: Uh = Ug = U{,

jg

jg + ji

where Uh is the homogeneous velocity, Ug is the gas phase velocity, Ut is the liquid phase velocity, sg is the homogenous void fraction, jg is superficial gas velocity and jt is the superficial liquid velocity.
