| "Physics-Based
Internal Air System Modeling"
A two-day short course in conjunction with Turbo Expo 2009
Saturday & Sunday, June 6-7, 2009
World Marriott Resort & Convention Center
Orlando, Florida
Overview and Objective
The overall purpose of this course is to develop a clear understanding
of the underlying flow and heat transfer physics and the corresponding
mathematical modeling and robust solution techniques for various components
of an internal air flow system designed for cooling and sealing of critical
parts of modern gas turbine engines.
After completing the course the participants should be able to:
- Recognize flow and heat transfer physics of various components of
gas turbine internal air systems
- Design more accurate and solution-robust internal air flow network
models
- Detect input and modeling errors in their flow network models
- Interpret results from their models for design applications
- Significantly improve their engineering productivity and company’s
design cycle time
