slides

The aim of the course is to provide the fundamentals of turbomachinery.

CC2: Knowledge and understanding of the relevant laws of physics (mechanics, electromagnetism, thermodynamics) and chemistry in the field of industrial engineering and understanding of the role of these laws in the formulation of representative models of tangible reality.
CC4: Knowledge and understanding of thermodynamics applied to energy systems and of fluid-dynamic phenomena as well as models capable of representing them. Knowledge of systems and machines for the production and conversion of energy, with particular reference to turbomachinery and industrial combustion equipment. Understanding the role of different energy technologies in ensuring the environmental and economic sustainability of production.

CA2: Applying knowledge and understanding related to the physical and chemical field to solve mono-disciplinary problems of chemistry, applied chemistry, mechanics, electromagnetism and theoretical thermodynamics as a basis for mechanical engineering problems.
CA4: Applying knowledge and understanding related to analytical modelling and experimental methods to design, analyze and test fluid machines, thermal motors and energy conversion systems. This includes: the application of design criteria for technical and thermos-technical plants, fluid and energy distribution; the application of thermodynamic principles to simple systems; the understanding of the main thermodynamic cycles and the reading of thermal diagrams; the identification of significant heat transmission mechanisms for engineering applications; the analysis and functional design of equipment of mechanical interest such as turbomachinery, energy conversion systems and internal combustion engines; the evaluation of the energy, economic and environmental performance of fluid, thermal and oleo-dynamic machinery.
