Phenomenological Modeling of Two-Phase Flow for LWRs. 1. Experimental Study of Hydrodynamics of Inverted Annular Flow. 2. Simulation Study of Hot Leg U-Bend Two-Phase Flow

摘要

In FY 1984 three specific tasks which are all related to not-well-understood two-phase phenomena of importance to LWR accidents have been identified under the program. These three tasks are: (1) inverted annular flow experiments and modeling; (2) hot leg U-bend two-phase flow simulation study; and (3) development and evaluation of two-phase flow scaling criteria. Some of the important results obtained under Tasks (1) and (2) are reported in this paper. (ERA citation 10:013059)
