Computational Fluid-Structure Interaction of Axial Pipe Waves and Application Towards Bruce 'A' NGS Flow-Induced Feeder Vibration - Phase 1

Abstract

Work was completed which compared predicted fluid-structure interaction results with published experimental results. The model used an impact force to induce stress and pressure waves along a straight pipe which was sealed and filled with pressurized water. Local strain and pressure values at several locations are plotted against time and are presented for visual comparison. The predicted results compare well with the published results and many of the major interaction effects are clearly observable. Application in subsequent work towards Bruce ‘A’ flow-induced feeder vibration is discussed.
