The effects of fluid particle interactions on interfacial transfer and flow structure
Abstract
Advancements in computer technology may permit the next generation of reactor thermal hydraulic analysis codes to implement highly detailed statistical approaches for the treatment of fluid particle distributions. This may significantly improve the code's ability to predict interfacial transfer processes. On September 30, 1990 a program was initiated at Oregon State University to compile a set of fundamental models for fluid particle coalescence and breakage frequencies for incorporation into a statistically based (Population Balance Approach or Statistical Monte Carlo Approach) twophase thermal hydraulics code. This report describes the progress achieved during the first seven months of the project. This report briefly describes the general framework into which the fluid particle interaction models can be incorporated. Also presented is an overview of the types of phenomenological models that have been identified as the result of a literature survey. The project objectives complement a research program at INEL aimed at developing an advanced twophase flow computer code. The project overview presented at the annual DOEOER review meeting at Savannah River Laboratory on April 2224, 1991 is included.
