Title: K-FIX; 3D; three-dimensional extension two-phase flow dynamics. [CDC7600; FORTRAN IV]

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 (NESC Abstract 727) 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.CDC7600; FORTRAN IV; SCOPE; The K-FIX(3D) sample problem, excluding plotting and timing routines, took about 50,000 (octal) words of small core memory (SCM) and 65,000 (octal) words of large core memory (LCM) storage. The K-FIX(3D,FLX) sample problem, excluding plotting and timing routines, took about 71,300 (octal) words of SCM and 570,000 (octal) words of LCM storage.
