• Semester 4, position 4

The goal of the course is to enable students to master the basic methods and techniques of measurement, as well as the processing of measurement results, in the field of thermodynamics and heat transfer. Through the independent performance of experiments in the laboratory, students acquire permanent theoretical and practical knowledge about the properties and equations of state of various substances, as well as the laws of thermodynamics and heat transfer.

Upon successful completion of this course, students should be able to: • Describe methods and master techniques for measuring individual properties (pressure, temperature, thermal conductivity of materials, heat transfer coefficient); • Process and present measurement results; • Determine measurement uncertainty; • Apply thermodynamic laws to various processes; • Determine the properties of state of working substances (ideal gas, water-water vapor and other pure substances) during their various thermodynamic state changes; • Explain the physicality and describe the laws of heat transfer.

General concepts of measurements. Fundamentals of statistical processing of measurement results. Measurement uncertainty. Basic principles of measuring the properties of a thermodynamic system - pressure and temperature. General laws of thermodynamics. Thermophysical properties of a working substance (pure substance, solid, liquid, ideal gas). Determining the energy measure of the performance of heat devices (heat engines, refrigeratоrs and heat pumps) that use energy from renewable and non-renewable sources. Laws of heat transfer (conduction, convection, radiation, combined heat transfer).

Laboratory exercises: 1. Contact temperature measurement using various methods. 2. Pressure measurement. 3. Experimental determination of the properties of state of various substances (ideal gas, water-water vapor) 4. Experimental confirmation of the Law of conservation of energy. 5. Use of energy from renewable sources - analysis of the operation of geothermal heat pump systems and solar thermal systems. 6. Determination of thermal conductivity of solid materials. 7. Experimental study of natural and forced convection. 8. Experimental study of the law of radiation. 9. Non-contact temperature measurement.
