Abstract

Abstract

The flow restrictor is simplified to the equivalent solid structure by the method described in ASME Appendix,and then the axisymmetry model and 3-D model are used for its solution.This paper com-pares the results from the two methods and their advantages and disadvantages in detail.It has been solved the SG steam outlet nozzle assembly,and furthermore demonstrated that the feasibility of simplifying the perforated structures to equivalent solid structures,and the reasonableness of 3-D model.
