STEAM AND GAS TURBINE ENGINEERING | MVK051 |

**Aim**

The course will provide the basic understanding of the construction and functioning of the components in a simple gas turbine and steam turbines. The focus will be on the gas turbines. Further more the course will provide basic skills in problem solving concerning energy balances at component and system level, the flow around the blades and vanes, simplified combustion analysis and calculation of efficiencies and losses.

*Knowledge and understanding*

For a passing grade the student must

- be able to describe the different components of the gas turbine cycle, i.e. the compressor, combustion chamber and expanders, and their way of functioning and design at a general level
- be able to describe functioning way of different types of turbines and their design at a general level
- be able to account for the flow phenomenon around the blades and energy exchange between the working fluid and the blade channels at a detailed level in written form
- be able to account for which operation and design parameters that influence the choice of the type of machine and their performance in written form as well as orally
- be able to calculate and account for component and system performance for any given system layout in written form
- be able to account for the process of designing the components of the gas turbine in written form at a general level

*Skills and abilities*

For a passing grade the student must

- be able to use the concept of efficiency to analyse and compare different component design and system solutions
- be able to calculate the stage performance based on the velocity triangles and energy balances, as well as the component design for any given design criteria
- be able to calculate the air flow and exhaust gas analysis for complete combustion of a given hydro carbon fuel and calculate the enthalpy of the exhaust gases

*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
