The drag functions for chunk ﬂow, plug ﬂow, and counter current ﬂow are more complicated and will not be addressed in this book. The viscous stresses appeared in Eqs. 80) for the gas phase. 83) for the liquid phase. The mean resistive velocity u for a phase and the eﬀective drag function for that phase K are deﬁned in terms of the interaction between phases Kn K ≡ K n with K n > 0. 85) K2 = K21 + K22 = K21 , since K22 = 0 . 86) Also Ku ≡ K n un . 88) K2 u2 = K21 u1 . 89) For the condition of momentum conservation, it is necessary K n = Kn ⇒ K12 = K21 etc.
