This subject deals with fluid energy machines, also called heat engines. For (A) turbo machines and (B) piston machines, the working principle and area of application are taught. These machines applications of the fundamentals learned in engineering thermodynamics and fluid mechanics. Examples are energy converters in wind turbines and power plants (solar, geothermal, tidal, gas-and-steam), media delivery in process engineering, fuel cells, mechanical and thermal storage power plants (pumped storage power plants, Carnot battery), mobile propulsion, pressure and vacuum supply in hydraulics, pneumatics, and vacuum technology, the delivery of hydrogen and methane via pipelines, and water and waste water delivery.
Part A (turbo machinery, lecturer: Brillert): The one-dimensional theory of hydraulic and thermal machines is explained. The most important equation of fluid machines, Euler's turbine main equation, and the connection with the velocity triangles is treated. For the applications in the above-mentioned systems, the operating maps and the operating behavior are discussed.
Part B (piston machines, lecturer: Kaiser): The relevant basics of thermodynamics are summarized and applied to the basic types of machines: piston pump, piston compressor, and reciprocating engine. Real processes and corresponding simplified models are discussed, in particular in the pressure-volume diagram. The designs, characteristic diagrams, machine elements and machine dynamics are explained for different areas of application.
