Abstract: Flow-induced acoustic resonances in piping with closed side branches cause severe structural vibration and fatigue damage of piping and components in power plants. Practical piping systems of power plants often have a steam ...

Abstract: When a water piping system operating under high temperatures and pressures is damaged and water is expelled into the atmosphere, a phenomenon known as depressurization boiling or flashing occurs. This flashing jet poses a ...

Abstract: Although acceleration and cumulative absolute velocity (CAV) are used as seismic indexes, their relationship with the damage mechanism is not yet understood. In this paper, a simplified evaluation method for seismic fatigue ...
