Pressure reduction devices such as valves and orifices in gas-filled piping systems can cause severe acoustic vibration and cause metal fatigue, particularly in systems with high pressure drops or high Mach number flows. This webinar focusses on the assessment of the risk of vibration induced by gas flow through pressure reduction devices, a phenomenon known as Acoustic Induced Vibration (AIV). The webinar combines the theory behind Acoustic Induced Vibration with a live demonstration using BOSfluids. By understanding and mitigating AIV, an early failure of the system can be prevented. This is especially of concern since AIV tends to affect safety related systems, as these for instance have a high-pressure drop or high Mach number flow over a relief valve. In addition, the time to failure is typically short as it involves a high frequency response.
