THEORY OF TURBO MACHINERY | MVK026 |

**Aim**

The course will provide basic knowledge and understanding of the principle of the turbomachinery, their construction, way of functioning and control and the processes that take place in these machines. Further more the course will provide basic skills in problem solving regarding energy balance at component and system level, interaction between the working fluid and the structure by simple analysis of the velocity triangles and calculation of the efficiencies and losses.

*Knowledge and understanding*

For a passing grade the student must

- be able to describe and sort different types of turbomachineries according to the function and area of utility at a general level
- be able to account for the process between the inlet and outlet of pumps, hydro turbines, fans and steam turbines at a detailed level in written form
- be able to account for the operation and design parameters that influences the choice of the machine type and their performance
- be able to calculate and account for component and system efficiency for any given system layout in written form

*Skills and abilities*

For a passing grade the student must

- be able to use factors of comparison and diagrams to choose the type of turbomachinery and design it for any given system and application
- be able to use the concept of efficiency to analyse and compare different system solutions
- be able to calculate the performance of the turbomachinery based on velocity triangles and energy balances
- be able to analyse measurement data for any given system in groups under supervision

*Judgement and approach*

For a passing grade the student must

- be able to actively participate in discussions regarding the relevant problems within the field of thermal power engineering
- be able to present analysis of calculation results from component and system analysis in written form

**Contents**

Elementary theory of turbomachinery working with compressible as well as incompressible working fluids.

The concept of losses and efficiency.

Methods for calculation and design of turbomachinery.

All types of turbomachineries (centrifugal & axial) that occur in industrial contexts are studied, i.e. pumps, fans, wind turbines, hydraulic turbines and steam turbines.
