Experimental study of the blockage effect of a vane anemometer in a small wind tunnel
Gregor Bobovnik, Peter Sambol, Jan Geršl, Jože Kutin
Izvirni znanstveni članek
Oznake: air velocity;wind tunnels;blockage effects;vane anemometers;intercomparison;
This study investigates the blockage effect of a vane anemometer in a small, closed test section of an open circuit wind tunnel. The experimental analysis examines the axial and cross-sectional positions of the vane anemometer in the test section. The results show that the changes in the calibration ...

Experimental investigation of a vane probe blockage effect in a small wind tunnel
Gregor Bobovnik, Peter Sambol, Jan Geršl, Jože Kutin
Izvirni znanstveni članek
Oznake: vane probe;laser doppler anemometer;wind tunnel;blockage effect;velocity perturbations;intercomparison;
The blockage effect of a vane probe with a high blockage ratio is investigated in a small, open-circuit wind tunnel with a box-type test section. A laser Doppler anemometer is utilized to determine a reference air velocity. The study examines how different cross-sectional and axial positions of the ...

Investigation of the discharge coefficient in the laminar boundary layer regime of critical flow Venturi nozzles calibrated with different gases including hydrogen
Gregor Bobovnik, Bodo Mickan, Peter Sambol, Rémy Maury, Jože Kutin
Izvirni znanstveni članek
Oznake: kritične Venturijeve merilne šobe;pretočni koeficient;eksperimentalne analize;pretok vodika;critical flow Venturi nozzle;discharge coefficient;experimental analysis;hydrogen flow;
This study represents the first step towards the introduction of critical flow Venturi nozzles into the traceability scheme for gaseous hydrogen and addresses the characterisation of the hydrogen discharge coefficient in the laminar boundary layer regime and the identification of a potential alterna ...
