The main objective of the course is to supply the instruments for the study of fluid machines and thermal power generation plants, by means of the analysis of operating principles and fundamental equations of machines, the study of steam power plants, gas turbines and reciprocating engines, as well as of the machines which transfer energy to the fluid.
Oral lessons
Introduction to Fluid Machines
Energy requirement, primary energy sources, energy conversion and utilization.
Classification and operating principles of fluid machines. The first principle for open systems; continuity equation, energy equation and Euler equation for turbomachines; degree of reaction; Hugoniot equation.
Thermodynamics applied to machines: thermodynamic cycles, efficiencies of fluid machines and power plants.
Thermal Power Generation Plants
Steam power plant: turbine, steam generators, condenser; ways of increasing the cycle efficiency.
Gas turbine power plant; ways to improve the Joule cycle efficiency: regeneration, inter-cooling, after-burning.
Cogeneration and combined power plants.
Reciprocating engines: operating principle and thermodynamic cycles.
Machines which transfer energy to fluid
Dynamic compressors: principle of operation, characteristic curves.
Reciprocating and rotary positive displacement compressors (vane, lobe, and Lysholm screw compressors).
Dynamic pumps: head, characteristic curve, operating point, cavitation, parallel and series configurations.
Reciprocating and rotary positive displacement pumps.
