Detailed
description of topics:
The course
consists of two parts: one part is about off-design behaviour of gas turbines
(with simulation-practicum with GSP) and a part application.
Part 1:
Performance characteristics of gas
turbine components, procedures and computer programs for the calculation of
the static and dynamic part load behaviour of gas turbines, the effect of
ambient conditions on performance. Operating envelope, flow phenomena in
compressors: stall, surge, choking. Performance monitoring: trend analysis,
the use of parameter estimation techniques in case only limited data are
available.
Part 2:
In part 2 the student is expected to carry out an assignment with GSP,
consisting of the analysis and the generation of solutions for a practical example of the behaviour of a
gas turbine under deviating operational conditions, as component wear, a
different fuel , application of water- of steam injection. A report has to be
written, and discussed with the lecturers. A grade will be determined during
the evaluation.

Learning
goals:
The student must be able to:
-
describe the part load characteristics of
gas turbines and its relation to the functional characteristics of gas
turbine components
-
calculate gas turbine performance with
modern computational tools (i.e. GSP, Gas Turbine Simulation Program®)
-
analyse gas turbine performance under
different operational conditions such as ambient conditions and power
setting
-
analyse gas turbine performance under
different hard ware conditions, i.e. after wear, erosion, corrosion of
critical gas turbine parts and components
-
analyse gas turbine performance as a
function of installation design
