A mechanistic model which considers the mechanical non-equilibrium is described for two-phase choking flow. The choking mass flux is obtained from the momentum equation with the definition of choking. The key parameter for the mechanical non-equilibrium is a slip ratio. The dependent parameters for

Homogeneous equilibrium two-phase flows are characterized by important variations of the local Mach number. Indeed, the sound speed can be several orders of magnitude higher in the liquid phase than in the two-phase mixture. For the simulation of such flows, a numerical method which can handle accur
A flow model is formulated to analyze the single-and two-phase flow characteristics in the primary side of a vertical, inverted U-tube steam generator. Using the flow model, a pressure drop-mass flow rate curve is derived. It is shown that the curve has a negative slope and, thus, flow excursion ins
