Applied Thermodynamics - a.y. 2016/2017
SSD: ING-IND/10 - ING-IND/11
Period (Year/Semester): II/II
Required/expected prior knowledge: Mathematical Analysis I, Genera Physics I
The student must be able to identify thermodynamic systems and their energy interactions with the environment, in the various modes of exchange. He must understand and interpret energy models, thermofluidodynamic and thermo-hygrometric models. The student must also acquire the methodological-operational aspects of the Applied Thermodynamic that allow him to identify, formulate and solve common problems forthe industrial engineering sector, with a particular focus to energy processes, thermal analysis of systems and their interaction with the environment.
Tables of contents:
Integral form of the mass, momentum, energy and entropy balances. Gibbs equation. Closed systems: mechanical work, pressure-volume relation for the elementary work; pv and Ts diagrams; thermal irreversibility; energy conversion: Carnot cycle and maximum performance of thermal machines. Entropy postulate and its measureability.
Thermophysical properties calculations and graphical representations (pvT surface, ph, Tv diagrams).
Plant components: turbine, pump, compressor, heat exchanger, throttling valve.
Power systems: vapor plant: basic cycle and modifications (reheat and regenerative power vapor cycles), gas plant. Refrigeration and heat pump systems: basic cycles, modifications, refrigerants.
Phycrometrics: thermophysical properties, dry-bulb temperature and humidity chart, transformations.
Heat transfer. Heat conduction differential law and boundary conditions; steady-state case for a flat plate, a cylinder and a sphere. Radiation: black body, grey body, view factor relations, heat transfer in a cavity.Convection: laminar and turbulent flows, natural and forced convection, Nusselt, Reynolds, Prandtl and Grashof numbers. Correlations among dimensionless parameters.
