Training objectives
- The course aims to provide knowledge of the basic principles of thermodynamics, heat transfer and thermo-physics of buildings. Learning of these physical principles will enable the student to understand the complex phenomena of energy interaction between different systems and the energy interaction between man and the environment in which he lives.
Prerequisites
- Knowledge of Calculus and Physics
Course programme
- THERMODINAMICS - Definitions. First law. Reversible and irreversible processes: second law. Open systems. Single-component systems: liquid, solids, ideal gases. State equations. Thermodynamic diagrams for pure substances. Gas and vapor power systems. Refrigeration cycles. Multicomponent ideal gas: moist air. Use of psychrometric chart.
HEAT TRANSFER: Fundamentals of heat transfer. Balance equations. Thermophysical properties. Conduction: Fourier equation. Forced, free and mixed convection in single phase systems. The nondimensional groups of heat convection. Radiation: the fundamental laws of thermal radiation. Radiative exchange: black and grey surfaces. View’s factors.
THERMOPHISICS of the BUILDING: Umidity in structures and Glaser Diagram. Didactic methods
- In the academic years up to 2018-2019, the course took place in the classroom, through lectures and numerical exercises aimed at solving specific problems of thermodynamics, heat transfer and thermophysics of buildings.
In the academic year 2019-20, the teaching took place entirely in e-learning mode, with video lessons and exercises.
This year, the lessons will still be conducted in e-learning mode, given the persistence of the health emergency from COVID. Mainly video lessons and live streaming exercises will be held; in some cases pre-recorded lessons will be used and an attempt will be made to increase the practical exercises. Learning assessment procedures
- The exam consists in a written assignment and in an oral talk that are scheduled together with those of the course “Applied Acoustics and Lighting Techniques” (Prof. N. Prodi) which is integrated with the present Course.
The written assignment lasts 2h 30min and consists in the solution of three simple exercises. The first one is about thermodynamics, the second is on heat exchange and the third one is either on applied acoustics or on lighting techniques. The numerical data in the exercises are personalized to the candidates by referring to some of the student matriculation numbers. To solve the proposed exercises it is possible to employ table, books, notes etc, except internet connections or mobile phones.
To access the successive oral talk (usually scheduled after 7 – 10 days) it is mandatory to equal or surpass the minimal score of 15/30. For scores from 15/30 to 17/30 the access is considered “with a reservation” in the sense that at the oral talk the candidate will be asked to draft the solution of a problem, whereas for marks equal or higher than 18/30 the admission is “without reservation”. The validity of the mark in the written assignment is 12 months from the date of the exam.
The oral talk consists in questions related to the theory, with a minimum of three, or in the drafting and discussion of typical exercises whose topics cover all of the program developed in the frontal lessons. The final mark is assigned after the accurate evaluation of candidate’s preparation in both the written and the oral parts of the exam. Since the Course in integrated with “Applied Acoustics and Lighting Techniques” (Prof. N. Prodi) the same final mark is registered for both exams. Reference texts
