Learning outcomes |
The primary objectives of this course are:
1. To provide a thorough understanding of the principles governing turbomachinery.
2. To enable students to analyze and design pumps, turbines, compressors, and fans.
3. To develop computational skills for simulating turbomachinery performance using software like ANSYS Fluent, BladeGen, TurboGrid, and CFX.
4. To introduce experimental techniques for performance evaluation and validation.
5. To link theoretical knowledge with real-world applications in energy and aerospace sectors.
6. To give students a complete design-analysis-evaluation workflow by integrating theory, simulation, and experiments.
