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

  • Samuel Bajomo


  • Senior Heat Transfer Specialist, Engineering Services, completed his BEng, MSc in Mechanical Engineering at University College London, London, United Kingdom (UK), majoring in Materials Science and Structural Mechanics. He began his career with MW Kellogg working on mechanical design of pressure vessels and heat exchangers and later transitioned into the heat transfer group as Principal Heat Transfer Engineer. In 2012 he moved to Wood Plc, London, UK where he oversaw the thermal and mechanical design of heat exchangers and fired equipment for several major oil and gas and petrochemical projects. His experience spans front-end engineering design (FEED), requisition, detailed engineering, and oversight of equipment manufacture. Bajomo then operated as an independent heat transfer consultant, working with equipment manufacturers and end-users on a wide variety of troubleshooting and design verification projects. His exchanger design and practical industry experience brings a uniquely qualified contractor’s perspective to HTRI’s Engineering Services team. Bajomo also currently serves on the board of the Institution of Mechanical Engineers (IMechE), Pressure Systems Group, and is a CEng MIMechE.

  • Sean Hennigan


  • Principal Engineer, Engineering Services, holds BEng and MEng degrees in Chemical Engineering from the University of Bradford (UK), including internships in France from 1988 – 1990. He has spent 33 years at the Saltend chemicals manufacturing site in Hull, working first for BP Chemicals and since 2021 for INEOS Acetyls. His global support work spans modeling, analysis, design, operations, turnarounds, commissioning, troubleshooting, technology development, intellectual property, and training. In 2008 he became BP Chemicals’ Separations and Heat Transfer Advisor, specializing in ASPEN simulation and Xchanger Suite®, delivering thermal design and troubleshooting for hundreds of heat transfer applications. At INEOS, his role expanded to Process Engineering Advisor, adding CFD and reliability analysis. He joined HTRI in 2026. Hennigan has been a chartered engineer since 1998 and an IChemE Fellow since 2015.
