Fluid Dynamics – Simulation, Pulsation Studies and Operating Vibration Analyses

Fluid dynamic vibrations in their processes can possibly lead to significant malfunctions as regards effectiveness and availability. We are active in the analysis of fluid dynamic phenomena in plant engineering especially when dealing with:

  • Gas- or liquid conveying pipes
  • Pulsations/pressure pulsations (reciprocating pumps and compressors, flow-induced vibrations)
  • Transient processes (water hammer, valve actions)
  • Vortex shedding
  • Cavitation

With our portfolio of services we can offer you substantial support in the analysis, calculation and removal of the malfunction: 

  • Troubleshooting:
    - Experimental modal analysis and analysis of operational vibrations
    - Support, evaluation and analysis of operational vibrations
    - Fluid dynamic simulation (flow simulation)
  • Recommendation, design and initiation of countermeasures (fluid or structure)

In specialized analyses and with consideration of relevant rules and standards (e.g. VDI 3842, EI AVIFF, API 618, API 674), affected components of the plant are analyzed regarding potential excitation mechanisms:

  • Fluid dynamic simulation and/or analysis
  • Vibration analysis according to Energy Institute AVIFF Guideline (determination of damage mechanisms and failure risks)
  • Pulsation study
  • Recommendation, design and initiation of countermeasures (fluid or structure)
