| Main themes |
The main focus of these lectures is directed towards axial steam and gas turbines. The description of radial gas turbines, as well as their operation, is of less importance. A short description of hydraulic machines ends the lectures.
|
| Aims |
Explain the fundamental principles of design and operation of axial and radial turbomachines (turbines)
|
