Title: K-FIX (3D). 3D Extension 2-Phase Flow Dynamics

Abstract

This package consists of two programs K-FIX(3D) and K-FIX(3D,FLX) which extend the transient, two-dimensional, two-fluid program K-FIX to perform three-dimensional calculations. The transient dynamics of three-dimensional, two-phase flow with interfacial exchange are calculated at all flow speeds. Each phase is described in terms of its own density, velocity, and temperature. The application is to flow in the annulus between two cylinders where the inner cylinder moves periodically perpendicular to its axis. K-FIX(3D) is easily adaptable to a variety of two phase flow problems while K-FIX(3D,FLX) combines KFIX(3D), the three-dimensional version of the KFIX code, with the three-dimensional, elastic shell code FLX for application to a very specific class of problems. KFIX(3D,FLX) was developed specifically to calculate the coupled fluid-structure dynamics of a light water reactor core support barrel under accident conditions. Motion may be induced by blowdown, prescribed displacement, or seismic action.

Resource Relation:
Other Information: DN: Memory must be preset to zero when loading the programs and the parameter LCM=I must be added to the FTN card of K-FIX(3D,FLX) to allow proper indexing of very large arrays. Dependence on CDC system features and the local plotting and timing routines requires modification and incorporation of suitable replacement routines for implementation on different systems and in other computing environments.; PBD: 1 Jan 1979
