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

HTRI Software

This course will make use of the following HTRI software: Xchanger Suite® components Xist® and Xvib®. All training materials are based on the current software version.

Course Credits: 6 hours (PDH/CEU)

Upcoming Instructors

  • Matthew Berger


  • Senior Project Engineer, Engineering Services, graduated with a BS in Mechanical Engineering from Texas A&M University, College Station, Texas, USA. While a co-op student at Gibbons Creek power plant, Berger performed performance reviews of pumps, pulverizers, and feedwater heaters. Following graduation, he progressed to project engineer and engineering manager roles for FTS International, leading engineering projects on various topics such as pulsation control, equipment redesign, software implementation, and vibration analysis. Since joining HTRI, his primary focus has been on proprietary contracts and the Edgeview software, as well as involvement in Technical Support and Training.

  • 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.
