Xist Workshop (US$450)
Instructor: Peter Joosten
This workshop is devoted to the shell-and-tube exchanger geometries handled only by Xist. The course 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 interface and the benefits of HTRI methods
- Process specifications rules for rating, simulation, and design
- Guidelines for specifying fluid properties
- Description of Xist geometry input parameters and their defaults
- Interpretation of Xist outputs for validation of unit performance
Suggested Participants
Designers of shell-and-tube heat exchangers and process engineers who evaluate their performance
HTRI Software
This course will make use of the following HTRI software: Xchanger Suite® component Xist®. All training materials are based on the current software version.
Course Credits: 6 hours (PDH/CEU)

Manager, Technical Support & Sales Manager Australia/Oceania, works with HTRI’s Engineering Services and Global Sales teams. His principal responsibilities include developing and conducting training programs, providing technical support, and promoting membership in the HTRI consortium. He earned a Bachelor of Mechanical Engineering degree from Fontys University of Applied Science, Venlo, The Netherlands. Prior to joining HTRI, Joosten was a Senior Heat Transfer Engineer at W. E. Smith Engineering, Coffs Harbour, Australia. His primary role was the thermal design and analysis of all types of shell-and-tube exchangers, air coolers, economizers, feedwater heaters, and steam surface condensers. He was also responsible for the mechanical design and stress analysis of these units, as well as for analyzing and resolving operational issues. His previous experience with HTRI software gives him a valuable end-user perspective.
