Simulation of the fluid–structure-interaction of steam generator tubes and bluff bodies
Autor: William Holmes, Steve Reuss, Amarvir Chilka, David Schowalter, Karl Kuehlert, Stephen W. Webb
Publikováno v: Nuclear Engineering and Design. 238:2048-2054
The accuracy of computational fluid dynamics in simulating the cross-flow around a steam generator and the feasibility of a full scale coupled CFD/FEA fluid–structure-interaction (FSI) analysis is examined through successive validations. The study

On the Choice Between Segregated and Coupled Solver Approaches When Using Computational Fluid Dynamics for Gas-Cooled Reactor Analysis
Autor: Nilanjana Basu, David Schowalter, Richard R. Schultz, Ajey Y. Walavalkar
Publikováno v: Nuclear Technology. 158:80-82
In this study, computational fluid dynamics solutions are obtained for a General Atomics GT-MHR reactor core under a depressurization scenario involving highly compressible flow. It is found that w...

Hydraulic Modeling of Air-Entraining Vortex Formation During Flow Withdrawal From Water Storage Tanks
Autor: David Schowalter, Andrew Johansson, Mahadevan Padmanabhan, Stuart Cain, Bryan Meyer
Publikováno v: Volume 3: Thermal Hydraulics; Current Advanced Reactors: Plant Design, Construction, Workforce and Public Acceptance.
In response to recent U.S. Nuclear Regulatory Commission (NRC) Component Design Bases Inspection (CBDI) issues, many US nuclear power stations have been required to demonstrate that minimum submergence requirements were properly determined for flow w

Unit-Tests Based Validation and Verification of Numerical Procedure to Predict Vortex-Induced Motion
Autor: Sung-Eun Kim, Ahmad Haidari, Indradeep Ghosh, David Schowalter
Publikováno v: Volume 4: Terry Jones Pipeline Technology; Ocean Space Utilization; CFD and VIV Symposium.
Vortex-induced vibration of a circular cylinder with two degrees-of-freedom (2-DOF) is numerically studied using a mixed Lagrangian-Eulerian approach at several Reynolds numbers. The computations were carried out using a parallelized finite-volume Na

Fluid-Structure Interaction of a Steam Generator Tube in a Cross-Flow Using Large-Eddy Simulation
Autor: Stephen W. Webb, David Schowalter, Karl Kuehlert, Mandar Joshi
Publikováno v: Volume 3: Structural Integrity; Nuclear Engineering Advances; Next Generation Systems; Near Term Deployment and Promotion of Nuclear Energy.
The behavior of a steam generator tube in a cross flow is examined by coupling the ABAQUS structural analysis code to Large-Eddy Simulation (LES) within the FLUENT Computational Fluid Dynamics solver. The moving tube is assumed to be within an infini
