Course content
|
The course will deal with the theoretical basis and practical measurements using experimental methods: 1. Thermoanemetry: System settings, calibration of thermoanemometric probes for CTA mode, measurement of velocity fields of flow from a continuous nozzle and a nozzle of synthesized current, evaluation of measured data. Measurement of the heat transfer coefficient on a heated plate. 2. Particle image velocimetry (PIV): System settings for 2D, stereo PIV and 3D measurements, difference between TomoPIV and Shake-the-Box methods, system calibration, explanation of the term "ghost particles" and "self calibration", current field measurement, determination of pressure fields from measured data, evaluation of measured data. 3. Laser Induced Fluorescence (LIF): System settings, temperature field measurements, particle concentration measurements, evaluation of measured data. 4. Laser Doppler Vibrometry (LDV): System settings, measurement of membrane displacement, evaluation of measured data. 5. Digital holographic interferometers (DHI): System settings, image processing, DFT, FFT, noise, its characteristics and methods of noise suppression, measurement of temperature fields (air, water), evaluation of measured data. 6. Thermocamera: Principle of measurement, influence of emissivity on obtained results, evaluation of data measurement. 7. Cavitation: The origin of cavitation and its effect on various materials.

Learning outcomes
|
The course deals with the theoretical basis and practical measurements using experimental methods.
Students will master the work in the laboratory, the ability to prepare and perform an experiment, analyze the measured data. Students will gain basic knowledge about individual experimental methods, which can then be further developed.
