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

  • Kevin Farrell


  • Principal Engineer, Computational Simulation & Validation, graduated from Pennsylvania State University, State College, Pennsylvania, USA, with his BS, MS, and PhD in Mechanical Engineering. His areas of expertise include fluid dynamics, vibration, and thermal engineering. His responsibilities at HTRI focus on flow-induced vibration, computational fluid dynamics (CFD), visualization studies, and fired heaters. Prior to joining HTRI, he worked for 16 years as a researcher and deputy head of the Fluid Machinery Department of the Applied Research Laboratory (ARL) at Pennsylvania State University. A member of ASME and ASTFE, Farrell is a licensed Professional Engineer (PE) in Pennsylvania and Texas, USA.

  • Andy Mountford


  • Senior Technical Lead, Training, provides technical support and training for HTRI. He earned a BSc and MSc in Chemistry and a PhD in Organometallic and Materials Chemistry from the University of East Anglia, Norwich, UK. During his tenure there, he conducted research at Wolfson Laboratory for Materials and Catalysis. He previously held the position of Thermal Design Supervisor at Tecnicas Reunidas in Madrid, Spain, gaining valuable experience using HTRI methods and software. Mountford oversaw the development of several high-profile PWR and BWR nuclear plant projects, as well as gained valuable experience in the thermohydraulic design of heat transfer equipment for the petrochemical and nitric acid/nitrates industries. His experience in using HTRI Xchanger Suite makes him uniquely qualified to bring an end-user’s perspective to the HTRI training program and to share techniques for effectively working with the software.
