## Thermodynamics and energetics I

Haussener Sophia

English

#### Summary

The course introduces the basic concepts of thermodynamics and heat transfer, and thermodynamic properties of matter and their calculation. The students will master the concepts of heat, mass, and momentum conservation, and apply these concepts to thermodynamic cylces and energy conversion systems.

#### Content

Generalities and fundamentals: Thermodynamic systems; Zero's Law; Energy and the First Law; Entropy and the 2nd Law; 3rd Law; Gibbs equations.
Closed systems and basic relations: Fundamental equations for homogeneous closed systems; specific heats, mathematical relations between state functions and various factors.
Open systems in steady-state: Elements of gas dynamics, nozzles, turbine and compressor efficiencies, etc.
Thermodynamic properties of matter: State and state changes, kinetic gas theory, perfect gas and ideal gas; state equations (Van der Waals, Lee-Kesler, etc.), approximate relations for liquid and solids.
Thermodynamic processes and diagrams: T-s, h-s, p-v diagrams.
Exergy: definition, exergy balance.
Elementary energy systems analysis applied to reversible cycles and of simple real cycles: Generalities; general properties of cycles; cycles with two thermal sources for engines and heat pumps.

#### Keywords

Thermodynamics, energy, matter, cycles

#### Learning Outcomes

By the end of the course, the student must be able to:
• Compute the thermodynamic properties of a fluid, E2
• Compute the main thermodynamic transformations of compressible and incompressible fluids, E4
• Formulate mass, energy, and momentum balances, E1
