Understanding and mastering basic thermodynamic principles and laws. Knowledge of thermodynamic states of working materials involved in energy transformation processes. Students will master theoretical and practical knowledge of steady state heat transfer problems. Based on the acquired knowledge, they will be able to recognize and solve practical problems encountered by engineers in practice.

Upon successful completion of the course, students should be able to: Interpret, explain and apply the first principle of thermodynamics to thermodynamic systems. Interpret and apply the equations of states of ideal and real gases. Recognize the problems of stationary heat transfer. Explain and apply them to determine the critical insulation diameter. Interpret, explain and apply the basic laws of thermal radiation in the calculation of radiation between two surfaces. Interpret, explain and apply combined heat transfer problems.

Basic thermodynamic concepts. Thermodynamic system, state quantities, state changes. Postulates of thermodynamics. Energy of the system, internal energy, ways of energy transfer, heat, work. The first law of thermodynamics for a closed system. Heat capacity, specific heat capacity of gases. The first law of thermodynamics for an open system. Basics of energy transfer by heat: conduction, convection, radiation, combined transfer. Heat conduction - basic concepts, Fourier's law, Fourier's differential equation. Stationary heat transfer problems: flat and cylindrical wall. Application of stationary heat transfer for determination of critical insulation diameter. Numerical solution of the problem of stationary heat conduction. Thermal radiation - basic mechanisms, wave and quantum theory, basic laws; radiation between two surfaces.

Calculation examples: Determining the state quantities. The first law of thermodynamics for a closed system, the amount of heat, the work done, the energy change of the thermodynamic system. Heat capacity, specific heat capacity of gases. The first law of thermodynamics for an open system. Ideal gases.
