Xist Workshop

Course Fee: US$450

Even if your work is limited to shell-and-tube heat exchangers, there’s much to be learned! This workshop is devoted to the geometries handled only by Xist. The day focuses on the extensive options available in Xist and how you can use these methods effectively to solve several example problems. You will leave the class knowing how to take full advantage of the features this robust tool offers.

Key Topics

  • Overview of Xist capabilities and applications
  • Geometry input for shell-and-tube heat exchangers
  • Process specifications for rating, simulation, and design
  • Guidelines for specifying fluid properties
  • Introduction to vibration analysis

Suggested Participants

Designers of shell-and-tube heat exchangers and process engineers who evaluate their performance

Upcoming Instructors

  • David Frankum


  • Senior Engineer, Technical Support, provides technical support and training for HTRI. He earned a BSc in Mechanical Engineering from the University of Birmingham and a PhD in Chemical Engineering from the University of Nottingham. Before joining HTRI, Frankum worked for Aspentech as a Team Leader in technical support. He also has experience with UKAEA as a technical/quality manager in the separation processes service. Frankum’s research experience, along with his knowledge of a wide range of heat exchanger-type equipment and design software packages (EDR, HTC, B-JAC, HYSYS, Aspen plus, and Xchanger Suite), gives him a broad-based skill set for his role at HTRI.


  • Andy Mountford


  • Senior Consulting Engineer, Technical Services and Sales, 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.


  • Patrick S. Redmill


  • Senior Engineer, Software Development, graduated with a BS in Chemical Engineering from Auburn University, Auburn, Alabama, USA, and then earned his PhD in Chemical Engineering from Vanderbilt University, Nashville, Tennessee, USA. While at Vanderbilt, he worked as a lab instructor and lecturer in the summer Pre-Engineering Program. His fields of specialization include large-scale scientific computation and molecular dynamics simulation. Redmill joined HTRI after working as a Software Developer on ProMax® at Bryan Research & Engineering, Bryan, Texas, USA. At HTRI, he has worked on updating the Xchanger Suite 7 online help and on maintaining Xist and Xace calculation engines. Redmill is currently evaluating heat transfer and pressure drop correlations for the next version of Xchanger Suite.


  • Ashley Simmons


  • Engineer, Technical Support, graduated with a BS in mechanical engineering from Texas A&M University, College Station, TX. During her studies, she completed two internships with oil & gas equipment company Proserv, gaining experience with product testing and technical writing. She worked in heat exchanger sales, covering the Houston, Waco, and Dallas/Fort Worth areas, for almost two years before joining HTRI. As a member of the Engineering Services group, she focuses on technical support and contracts but also assists with development of other materials for HTRI's technical program.
