Syllabus
Prerequisites: Requirements for the course are the basic concepts of differential calculus and thermodynamics acquired from the student in the courses of the first year.
It is given for acquired the concepts: energy, power, heat, work, temperature, Carnot's cycle, the first law of thermodynamics, perfect gas theory.
Target skills and knowledge: The course supplies the engineering bases with to face the various within of energy management both on a large scale (energy conversion plants) and on small scale (energy requirement of the inhabited structures).
The course presents the main applications to engineering of the Physics course basic concepts (temperature, heat, work, etc), the Thermodynamics laws; in particular will be facing the real thermodynamic cycles (derived from the Carnot's cycle) with attention to the production of electric power and the refrigeration. The course introduces the heat transfer with reference to the applications to the building structures and the heat exchangers used in the conversion plants.
The heat transfer analysis will come moreover finalized to the understanding of the interaction of the human body inside a confined system (air conditioning).
Examination methods: The examination is based on 2 contextual written tests (that is not separable): a numerical test and a theoretical one with 2-3 opened questions, the final vote in 30th is the sum of the two single tests in 15th.
Assessment criteria: The student should demonstrate to master the theoretical learned skills and to know to manage the calculation and design instruments viewed during the course. He should be able to apply the theory to the real engineering cases and in particular to civil applications.
Course unit contents: Dimensions and unit systems: fundamental and derived dimensions, International system, Technical system, English system, conversion tables.

APPLIED THERMODYNAMICS
Temperature and the zeroth law of thermodynamics.
The first law of thermodynamics: heat, work, temperature. System and control volumes, closed and open systems. Examples of a reversible process. Internal energy and enthalpy.
The second law of thermodynamics: Kelvin-Planck and Clausius statements. Heat engine. Energy efficiency. Carnot cycle. Carnot principles. Clausius equality and disequality. Entropy.
Perfect gases: equation of state. Specific heats for perfect gases. State relations for perfect gases.
Processes for perfect gas: constant pressure, constant volume, isothermal, isoentropic process.
Pure fluids: diagrams of properties. Gibbs relation (free energy). p-v-T data for pure fluids.
T-v, p-v, p-T diagram. Saturated vapour, vapour quality. Superheated vapour and subcooled liquid.
h-s Mollier diagram. T-s ammonia diagram. p-h R134a diagram. Saturation tables.
Vapour power cycles: Rankine cycle, reheat cycle, Hirn cycle.
Gas power cycles: Otto and Diesel cycles. Gas turbine cycle (Brayton-Joule cycle).
Reversed cycles: heat pump and refrigeration cycles. Coefficient of Performance. Double compressions cycle.

HEAT TRANSFER
Steady thermal conduction: Fourier's law, substances thermal conductivity. Thermal resistance.
Natural and forced thermal convection: basics and practical parameters use.
Overall heat transfer: overall heat transfer coefficient, building structures application.
Heat exchangers: basic analysis, thermal profiles, tube-in-tube heat exchanger design. Thermal effectiveness. Log mean temperature difference.
Planned learning activities and teaching methods: Theoretical frontal lessons and numerical practices necessary for the examination test.
Additional notes about suggested reading: Besides the advised texts, the exercises carried out during the lessons, the unit conversion tables, the diagrams, the tables of the fluid properties used during the course will be uploaded and downloadable by Moodle platform.
