At Mechartes, we offer in-depth studies of Flow-Induced Vibration (FIV), Flow-Induced Turbulence (FIT), and Acoustic Induced Vibration (AIV) to enhance the performance and reliability of fluid-handling systems.

Our FIV studies assess vibrations in structures or equipment caused by the interaction between fluid flow and the equipment’s geometry. We analyze how fluid flow dynamics contribute to vibrations in piping systems and heat exchangers, which can lead to mechanical fatigue, structural damage, and operational inefficiencies if not properly managed. Our analyses provide crucial insights into the types and magnitudes of vibrations, allowing us to recommend effective mitigation strategies.

In FIT studies, we examine turbulent flow patterns that occur when fluids move through or around structures, using advanced Computational Fluid Dynamics (CFD) simulations to visualize and predict turbulence. This analysis helps us understand how turbulence impacts system performance, contributing to issues like increased pressure drops and noise. By optimizing design and operational parameters, we can reduce these adverse effects and improve overall system efficiency.

AIV or Acoustic Induced Vibration is a distinct mechanism where intense acoustic energy generated downstream of pressure-reducing devices (e.g., relief/letdown/control valves, orifice plates) can excite circumferential “shell” modes of thin-wall pipe, causing high-cycle fatigue, typically at tees, reducers, and welds in gas lines. Screening uses acoustic power/level correlations (e.g., Carucci–Mueller) and thickness/diameter checks (e.g., Eisinger D/t-based criteria) as referenced by EI. Detailed checks and mitigations (geometry, wall-thickness changes, staged pressure drops, low-noise trims) follow when screening flags elevated risk.

Through our expertise in FIV, FIT, and AIV studies, Mechartes ensures that your fluid-handling systems operate smoothly and reliably, addressing potential issues proactively to maintain optimal performance and safety.
