Special Topics in Xace Short Course

Course Fee: US$650

Improve your understanding of the methods in Xace and develop new skills to model difficult cases. This short course focuses on improving thermal predictions, interpreting results, troubleshooting cases and applying workarounds. Even the most experienced thermal designers will gain new insight into how to improve thermal analyses using Xace.

Case studies may include:

• Rating natural draft (fans-off) cases
• Improving accuracy of predicted driver power
• Modeling units with redundancy fans (3x50% fans)
• Multiple service units
• Inert blanketing in air-cooled condensers

Suggested Participants

Experienced Xace users who rate, design and troubleshoot air-cooled heat exchangers

Course credits: 6 hours (PDH/CEU)
