Flow-induced vibration (FIV), or vortex shedding, may be either self-induced, i.e. due to piping obstructions and T-junctions, or forced, i.e. generated by machinery such as reciprocating compressors and pumps. At specific frequencies, flow pulsations excite acoustic resonances, producing high pressure pulsations that may excite mechanical resonances, produce high vibrations, or cause fatigue failure.
S.A.T.E. S.r.l. provides consultancy services for dynamic simulations of pressure pulsation in fluid plants, due to reciprocating machines, rotary compressors, axial and centrifugal turbomachinery, and vorticity in piping diffusers, dead branches, or junctions, with the scope of allowing design engineers and operators to control FIV and the corresponding physical parameters.
The solutions proposed allow to investigate the acoustic and mechanical response of a fluid plant interacting with machinery and to identify remedy actions to control or limit vortex shedding effects, exploiting the proprietary software suites:
- ACUSYS®: Simulation of pressure pulsation in fluid plants, by interaction with reciprocating machines or self-excited vortex flows;
- ACUSCOMP™: Dynamic simulator of reciprocating compressors interacting with piping flow and pressure dynamics;
- MECHDYN™: Complete static and dynamic analysis of beam-like mechanical structures;
- HYDRODYN™: Dynamic simulator of single-phase flow in piping and plants for seals barrier fluid analysis, suitable for turbulent low subsonic flow conditions.
