Owen-1 - a code for analysis of two-phase compressible flow transients in a single channel.

Abstract

A computer code for simulating two-phase compressible flow transients including loss-of-coolant in a single water cooled channel is described. The momentum flux term is included and slip between the phases is allowed. A pipe model and detailed surface heat transfer is included. The conservation equations are solved by means of an implicit numerically stable finite difference scheme so that time step size can be chosen on accuracy considerations alone.
