Xvib Workshop

Course Fee: US$450


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

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.


  • 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 ISA, Farrell is a licensed Professional Engineer (PE) in Pennsylvania and Texas.
