Detailed data on research infrastructure/laboratory
- Description and data on research infrastructure/laboratory:
The laboratory is dedicated to the research of heat and mass transfer in the vicinity of heated surfaces using holographic interferometry. A non-contact optical method is used to record temperature fields and temperature boundary layers in the vicinity of heated heat exchange surfaces of various shapes (e.g. tubular and plate heat exchangers, thermowood). In addition, physical quantities (temperature, velocity, pressure, flow rate) are obtained using sensors connected to the Almemo data logger. The resulting temperature fields and physical parameters can then be used to calculate the heat transfer parameters necessary for further optimisation of heat exchange surfaces and heat exchange processes. -

Reasoning for uniqueness/strategic importance:
The holographic interferometry method provides real-time, non-contact recording of temperature fields in the vicinity of heated surfaces. The recorded interferograms can then be used to evaluate heat transfer parameters and to suggest possible intensification of heat transfer and shape optimization of heat exchange systems. -
