Xvib Workshop

Course Fee: US$450

Download Course Details

Because vibration can cause critical operating problems in heat exchangers, it is important to analyze the potential for flow-induced vibration.

This workshop teaches you how to develop an input file, interpret results, and obtain accurate prediction of the vibration potential for installed units. Using Xvib you’ll practice determining if a heat exchanger is susceptible to vibration damage.

Key Topics

  • Analysis methods for fluidelastic instability and vortex shedding
  • Velocity profile development
  • Vibration susceptibility

Suggested Participants

Engineers responsible for the mechanical condition of shell-and-tube heat exchangers

Course credits: 6 hours (PDH/CEU)

Upcoming Instructors

  • Salem Bouhairie


  • Senior Project Engineer, Research, earned his BEng, MEng, and PhD in Civil Engineering from McGill University, in Montreal, Quebec, Canada. While pursuing his graduate studies, he taught Water Resources and Hydraulic Engineering as an Adjunct Professor; Bouhairie also worked as a Laboratory Experimenter in open-channel hydraulics. Following his graduation, he became a Research Assistant at the university, gaining additional expertise with CFD in modeling fluid flows. He worked at Northwest Hydraulic Consultants, in Edmonton, Alberta, Canada, where he conducted physical hydraulic modeling investigations and river hydrology assessments. This experience gave him a broad-based knowledge of heat and mass transfer, thermal- hydraulic design, and computational methods. Bouhairie has delivered presentations on his work in Canada, the United States, England, and Brazil; his work has been published in the Journal of Fluid Mechanics and the Journal of Hydro-environment Research.
