A generic semi-implicit coupling methodology for use in RELAP5-3D

摘要

A generic semi-implicit coupling methodology has been developed and implemented in the RELAP5-3D computer program. This methodology allows RELAP5-3D to be used with other computer programs to perform integrated analyses of nuclear power reactor systems and related experimental facilities. The coupling methodology potentially allows different programs to be used to model different portions of the system. The programs are chosen based on their capability to model the phenomena that are important in the simulation in the various portions of the system being considered and may use different numbers of conservation equations to model fluid flow in their respective solution domains.
