Case Studies
About Case Studies
A Case Study is a presentation describing the successful implementation of established technology to solve a real-world problem.
Case studies are written with end-users in mind. They are not published in the symposium Proceedings, but are provided in the symposium materials bag on CD to all attendees.
The presentations typically consist of 10 to 20 slides or transparencies, and are limited to 15 minutes, with an additional five minutes provided for questions.
Below is the list of case studies that will be presented at the 37th Turbomachinery Symposium:
