Method and system for modeling valve dynamic behavior using computational fluid dynamics

摘要

A system for modeling fluid flow in a valve (10) includes a section for modeling a main fluid flow domain having an inlet (25), a first outlet (26) and a second outlet using a first grid size, a section for modeling a leakage fluid flow domain (38) having an inlet that includes the main fluid flow domain second outlet and a leakage fluid flow outlet using a second grid size, and a section for iteratively calculating fluid flow in the main fluid flow domain based on leakage flow as determined by the section for modeling leakage fluid flow. Also a method for modeling fluid flow in a valve.
