Summary :

The proposed course is a three-credit gas turbine design course using a small scale turbo-jet engine as a teaching/design vehicle. The course is geared towards graduate students and senior level undergraduate students as a technical elective. The students will learn/improvise/design actual components that will eventually go into an operational test bed. The course instructor will lead the design groups and some of the grading will be based on the final presentations given to a design review board. Effective time management of project milestones will be encouraged and the students will be evaluated against (agreed) deadlines by the instructor. A number of lecturers from the gas turbine industry will be invited for design seminars and review meetings during the semester.

Summary

This course is intended to provide a thorough introduction to the basic ideas employed in the application of finite element techniques to especially fluid flow and heat transfer problems. A student who successfully completed this course should be able to perform quick analysis of small problems using the finite element method and write full sized application codes for analyzing fluid flow and heat transfer problems. Additionally, mastery of the material provided in this course will enable the student to more intelligently use commercially available codes based on the finite element method.
