Fluid Metrology Facility conducts scientific research on measuring the energy quantity in a given flow and the automation of research processes, especially those associated with thermodynamic and kinematic parameters and stationary and non-stationary fluid stream.
This facility works on:
- improving and advancing the methods of assessing the pressure, temperature and speed in steady and unsteady-, one-, two- and three-dimensional flow.
- methods of calibration: designing stations for automatic, multiparameter, static calibration of pneumatic and electrical converters of thermodynamic and kinematic parameters of a fluid stream; analytical descriptions of static characteristics and incorporating neural networks into the calibration process.
- identification and correction of dynamic characteristics of temperature converters.
- distorting the non-stationary measuring signal in pneumatic part of electro-pneumatic slotted line.
- studying the non-stationary flow phenomena in:
- simple and branching tracks, pulse-powered,
- multi-stage machines, within their interaction between the steering wheels and turbine rotors (clocking effect), with additional research into attempting to establish an optimal position of the parts for the best efficiency of the turbines with the least amount of generated noise,
- radial compressors (measuring rapidly changing pressure),
- measuring spatial area of the noise emitted by a flow machine in order to establish a correlation between the clocking effect of blade-rings of the machine and lowering the noise generated by its turbine,
- photo-optical methods of the flow,
- automatization of research stations to enable “on-line” research methods,
- identification of approaching pump phase in radial compressors,
- analysis of temporal frequency of signals attained during experiments.
The facility has several unique research stations and measuring apparatus:
- no-echo aero-acoustic chamber of 386,5 m3 of functional volume and 368 m2 area,
- automated stations for static and dynamic calibration of converters,
- a station for pulsating flow of gas tracers,
- a non-stationary pressure generator,
- multiple sets of thermo-anemometric multi-channel apparatus with probes for measuring the speed of one-, two- and three-dimensional flow, by Thermosystem and Dantec,
- data acquisition stations: WaveBook, DaqBook and Keithley,
- acoustic measurement apparatus, such as: Pulse f-my Brüel & Kjær,
- pressure commutator f-my Scanivalve,
- specialized probes for time-varying pressure and speed in fluid stream and in boundary layers,
- two small aerodynamic tunnels for pneumatic and thermodynamic probes calibration,
- aerodynamic tunnel for research on flat palisades.
