3. Course objective
  This course covers a broad range of topics related with turbomachinery theory, application, design, and performance evaluation.

4. Course Description (IC-PBL+)
The following topics will be discussed:
  - The fundaments of vibration, thermodynamics, fluid mechanics, and mechanical design
  - Turbocompressors, gas turbines, turbopumps
  - Performance measurement and evaluation

 Prerequisites: Vibrations, Fluid Dynamics, Dynamics, Thermodynamics, Heat transfer

* Note that this class follows the IC-PBL+ format.

The IC-PBL+ is an "industry-linked, problem-based, project course method" focused on the development of various capabilities required for future leaders of society. As an advanced program of the IC-PBL, the program has been designed to provide students with a graduate-level educational experience to foster "scholars" with initiative, "co-workers" who are capable of performing industry-based research with interdisciplinary thinking, and international "leading researchers" with global researching capabilities.

 https://www.sbir.gov/sbirsearch/detail/408774

 https://www.sbir.gov/node/1413831

Each group will choose a topic for the class project based on the students' interest. At the end of the semester, the final report and presentation must show feasibility or preliminary (or even detailed) design for turbomachinery prototype development from your group topic.

The first weekly presentation must show the 1) Problem statement, 2) Goal, 3) Brief introduction, 3) Justification/Motivation, 4) Scope, 5) Tasks, 6) Methodology, and 7) Schedule for the project. Note that this class covers turbomachinery rotating components and their housings ONLY!! That means motors/generators (electric components), controllers, combustion chambers, and recuperators, etc are not our class subjects. Recall Template for weekly task plan.
