  • Heat Exchanger Troubleshooting Short Course (US$650*)
  • Course Description: Design decisions can have a costly impact on heat exchanger operation. In this course, you learn by reviewing several real cases in which unit designs had critical commercial consequences for operators/ owners. Among other topics, this course may address
    • assessment of acoustic vibration in rectangular ducted bundles (Xace®)
    • vibration analysis of a shell-and-tube heat exchanger (Xist® and Xvib®), including a review of the velocity scaling applied to tubes near impingement plate edges
    • sizing of annular distributor (vapor belt) and associated tube vibration analysis (Xist and Xvib)
    • root cause analysis of tube failures in a steam generator (a reboiler/steam drum configuration modeled as a thermosiphon reboiler in Xist)
    • design review of an air-cooler/condenser (Xace) with excessive tubeside pressure drop during winter operation
  • In some cases, the units did not work in service; in others, the designs were revamped before the units began operation. Each case study is introduced as a problem; participants work individually or in groups to determine the cause and develop solutions. Prior to each case, the instructor reviews related HTRI methods.

  • Design Challenges: Managing Flow Distribution and Vacuum Pressure Drop (US$650*)
  • Course Description: Commercial software uses a wealth of incremental data to assess the performance variations throughout a heat exchanger. Simplifying assumptions anchor these incremental data, sometimes leading to inaccuracies with challenging designs. Through four case studies, this course reviews the performance characteristics of challenging designs and discusses guidelines to attain accurate performance predictions. Two cases with high effectiveness are shown to be susceptible to performance shortfalls due to flow maldistribution, while two vacuum cases are examined for performance sensitivity to errors in modeling pressure drop. Novice and experienced heat transfer specialists will improve their understanding of the limits of the underlying research and the importance of judicious engineering assumptions.
