Course objectives supported by learning outcomes

The filling of the subject builds on the subject of Physics and is the basis for many technical disciplines. Students will deepen their knowledge of Thermodynamics of gases, heat, and learn the basics of combustion. These findings are a sine qua non for the understanding of the nature of economic production, transformation and distribution of thermal energy. Allows you to correct management of technological processes and is essential for a number of normal thermal technical calculations.

Syllabus

• 1. Basic concepts. Microscopic and macroscopic view. Thermodynamic system, state, action; the status exchanges. Reversible and irreversible state changes. The quantity of the substance. The internal energy. The state values, the heat, the work. Empirical temperature. The zero and the first law of thermodynamics 2. Calorie equation of State and thermal. The different models: an ideal gas, the gas temperature. Unideal gases, solids, liquids, and models. Radiation 3. Material quantity dependent on temperature, expansivity, degree of expansion, compressibility. Heat and temperature parameters. Calorimetrs 4. A simple system. Isotermal, izobaric, izochoric, adiabatic and polytropic process, p-V diagram 5. Thermodynamic machines: engine, refrigerator, heat pump. Second law of thermodynamics, Thomson’s and Carnot’s formulations, the relationships between them. The Wording Of Carathéodory’s 6. Carnot cycle, the efficiency of heat engines, entropy, thermodynamic temperature. The third law of thermodynamic. 7. The thermodynamic potentials: internal vacancies and the Gibbs energy, enthalpy. Their properties and applicability for a particular job 8. Real gases, the properties of liquids and vapours, tables, and charts properties 9. Phase vs. folder. Phase transitions, phase diagram. Claus and Claus-Clapeyron’s equation. The mixture of gas and filling of steam; -thermodynamic properties of moist air, Mollie’s diagram, h-s diagram processes with damp air 10.
