KFIX (3D). 3D Extension 2Phase Flow Dynamics
Abstract
This package consists of two programs KFIX(3D) and KFIX(3D,FLX) which extend the transient, twodimensional, twofluid program KFIX to perform threedimensional calculations. The transient dynamics of threedimensional, twophase 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. KFIX(3D) is easily adaptable to a variety of two phase flow problems while KFIX(3D,FLX) combines KFIX(3D), the threedimensional version of the KFIX code, with the threedimensional, elastic shell code FLX for application to a very specific class of problems. KFIX(3D,FLX) was developed specifically to calculate the coupled fluidstructure 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 KFIX(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
