This paper discusses the hydrodynamic equilibrium two-phase flow distribution phenomena in unheated subchannel systems. A set of two-fluid governing equations is solved and the solutions are compared with the equilibrium air-water two-phase flow experimental data from an inter-connected two-subchannel test section in the slug to churn-turbulent flow regime. It is shown that the two-phase flow under the hydrodynamic equilibrium condition is distributed to make the minimum of possible pressure gradients. It is also shown that this minimum pressure gradient is closely related to the minimum energy dissipation of the total flow system. Finally a model is proposed to predict the hydrodynamic equilibrium two-phase flow distribution in a rod bundle as a minimization problem of the energy dissipation with mass continuity and momentum balance equations as the constraints.
