RISDiscussion of “Flow Excited Acoustic Resonance Excitation Mechanism, Design Guidelines and Counter Measures,†(Ziada, S., and Lafon, P., 2014, ASME Appl. Mech. Rev., 66(1), p. 010802)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The authors have done extensive research in gathering historical background on the subject of flow excited acoustic resonance. They have provided extensive discussion to justify creative formulations for predicting the ...
Transient Thermal Hydraulic Responses of the Nuclear Steam Generator Secondary Side to a Main Steam Line Break1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a multidimensional numerical analysis of the transient thermalhydraulic response of a steam generator (SG) secondary side to a doubleended guillotine break of the main steam line attached to the SG at ...
Effects of a Venturi Type Flow Restrictor on the Thermal Hydraulic Response of the Secondary Side of a Pressurized Water Reactor Steam Generator to a Main Steam Line Break
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical analysis has been performed to simulate the transient thermalhydraulic response to a main steam line break (MSLB) for the secondary side of a steam generator (SG) model equipped with a venturitype SG outlet ...
Transient Hydraulic Response of a Pressurized Water Reactor Steam Generator to a Feedwater Line Break Using the Nonflashing Liquid Flow Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a computational fluid dynamics (CFD) analysis of the transient flow field inside the secondary side of a nuclear reactor steam generator (SG) during blowdown following a feedwater line break (FWLB) accident ...
Analytical Study of Flow Instability in a Natural Circulation Pressurized Water Reactor Auxiliary Feedwater System1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A pressurized water reactor (PWR) incorporates a passive auxiliary feedwater system (PAFS), a closed natural circulation loop which is aligned to feed condensed water to its corresponding steam generator (SG). During its ...
A Simplified Analytical Model for Estimation of the Initial Waterhammer Pressure and Force on a Circular Tube
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simplified analytical model is developed for estimating the initial waterhammer pressure and force on a circular tube when a plane decompression wave, parallel to its axis, passes over it. The simplified analysis ...
