## AIMS AND CONTENT

LEARNING OUTCOMES

This course is aimed at providing basic knowledge of applied thermodynamics and heat transfer, with specific attention to cycles, thermal plants,  thermo-fluids, heat transfer mechanisms. Theory will be integrated by practical exanples.

Teaching methods

Typically four hours/week for both first and second semester.

Interruptions of lessons (if any) will be announced by the teacher well in advance

SYLLABUS/CONTENT

First part:

Thermometry. Closed and open systems. Thermodynamic state and properties. Thermodynamic processes. Definition of heat and work. First law of thermodynamics for open and closed systems. Internal energy and enthalpy. Specific heat. Secon law of thermodynamics, Kelvin and Clausius definitions. TdS equations. Ideal gas: state equation, properties, fundamental processes. Pure substances: definition, properties, thermodynamic diagrams. Cycles: Carnot, Joule, Otto, Diesel, Rankine, calculation of efficiency. Inverse cycles:  Carnot, two-phase, calculation of efficiency.

Second part:

Thermodynamics of fluids: Bernoulli equation and its applications, pressure drop in pipes. Incopmressible and compressible fluids, Hugoniot equation.

Conduction heat transfer: Fourier law, equation of conduction in Cartesian and cylindrical coordinates. Finned surfaces. Transient conduction: lumped analysis.

Convection heat transfer: Boundary layer for external and internal flows, natural and forced convection, dimensionless analysis.

Radiation heat transfer: Black body, definition and laws. Heat transfer between black and gray bodies.
