Thermodynamics
Fundamentals: physical quantities and units of measurement, closed and open systems, forms of energy, properties of a thermodynamic system, transformations and thermodynamic cycles, temperature and zero principle of thermodynamics, pressure. The first law of thermodynamics: the concept of conservation of energy, closed and open systems, enthalpy, energy conservation for stationary flow systems. Properties of substances: pure substances, heat capacity and specific heats, phases of a substance, phase changes of pure substances, state diagrams, equation of state for ideal gases, transformations. The second law of thermodynamics: statements of the second law of thermodynamics, heat engines, refrigeration machines and heat pumps, reversible and irreversible transformations, Carnot cycle, entropy. Thermodynamics of humid air: dry air and atmospheric air, absolute humidity and relative humidity, dew temperature, psychrometric diagram, air conditioning, transformations for air conditioning.
Heat transfer
Steady-state thermal conduction: Fourier postulate, analogy with electrical flow, thermal conductivity, one-dimensional conduction in simple geometries, multilayer flat walls, cylindrical geometries, critical insulation radius. Forced and natural convection: introduction, dimensionless numbers, classification of fluid motion, limit layer of velocity and temperature, natural convection on surfaces. Irradiation: introduction, thermal radiation, black body radiation, radiative properties, view factors, heat transmission by radiation between black and gray diffusing surfaces, radiation screens. Applications: thermal transmittance and conductance of walls, critical insulation radius. Heat exchangers.
Acoustics
Acoustic quantities: general information, sound pressure and sound pressure level, sound power and sound power level, sound intensity and sound intensity level, psychophysical acoustics, normal audiogram, weighting curves. Free-field and indoor environment propagation: behavior of materials subjected to sound stresses, sound-absorbing and sound-insulating materials, sound-insulating power, sound insulation, Sabine theory.
