Goals and content

Learning Objectives:

Students will be able to:

  • describe and calculate the underlying physical-technical processes
  • apply the mathematical and thermodynamic descriptions
  • correctly reproduce the diagrams and schematics
  • explain and analyze diagrams
  • explain the operation of gas and steam turbines and their components
  • name the areas of application of thermal turbomachinery and assess their significance for power generation and drive technology
Course content:

In the first third of the lecture, the Institute of Technical Thermodynamics will lay the thermodynamic foundations for the lecture. This includes the definition and explanation of thermodynamic state variables and elementary changes of state as well as the discussion of technical cycle processes. In addition, elementary knowledge of combustion technology is conveyed in a concise form.

The subsection on reciprocating engines covers internal combustion engines, reciprocating pumps and reciprocating compressors. The topic of combustion engines covers the areas of components, inertia forces, thermodynamics, operating parameters, and emissions, and explains physical relationships using simple calculations. In the section on pumps, losses and simple calculations (NPSH) are explained in addition to basic principles based on static considerations. The chapter on reciprocating compressors deals with single-stage and multi-stage compression and the performance of compressors.

The last third of the lecture deals in the section Thermal Fluid Machinery with the basics, the mode of operation and the fields of application of gas and steam turbines for the generation of electrical energy and in drive technology.
