Aims :

The aim of this module is to provide the student basic tools for understanding thermodynamic proc-esses and heat transfer mechanisms, with particular focus on industrial engineering applications.

Topics :

Introduction to thermodynamics. Basics of thermometry. State thermodynamics. Thermo-dynamics sharts. Vapours, ideal gas, incompressible substances. First law of thermodynamics for closed and open systems. Application of first law to simple system components. Second law of thermodynamics. Clausius and Kelvin postulates. Direct and reverse thermodynamic cycles. Direct and reverse Carnot cycle. Entropy. Vapour and gas direct thermodynamic cycles. Vapour compression reverse thermodynamic cycle. Heat transfer mechanisms. Steady state conduction. Electric analgy and resistive model. Thermal convection. Flow regimes. A-dimensional numbers and correlations for practical use. Thermal radiation. Black-body and real-surfaces radiation. Heat transfer between black bodies, gray bodies within cavities. Heat transfer combined mechanisms. Walls transmittance. Enhanced heat transfer. Finned surfa-ces. Heat exchangers. Thermal conduction in dynamic state within negligible-internal-resistance systems.
