Abstract

Ovaj rad bavi se obradom eksperimentalnog profila brzine za uvjete nepokretnog dna. Za potrebe istraživanja vodotoka unutar kojeg se nalazi stup mosta poslužila nam je eksperimentalna metoda laboratorijskog ispitivanja u hidrauličkom kanalu koja nam omogućuje simuliranje željenih hidrauličkih uvjeta. Obrada podataka o brzini izmjerenih uređajem Vectrino 2 koji radi na principu Dopplerovog učinka omogućuje nam uvid u vertikalnu distribuciju brzina i turbulentnih karakteristika toka. Mjerenja u trajanju 12 minuta provedena su pri različitim protocima. Rezultati obrade svih mjerenja prikazani su grafički radi olakšanog uspoređivanja rezultata za različite protoka.

Abstract (english)

This paper deals with the analysis of the experimental velocity profile for immobile bed conditions. For the purposes of researching the watercourse within which the bridge pillar is located, we used the experimental method of laboratory testing in the hydraulic channel, which allows us to simulate the desired hydraulic conditions. Processing the velocity data measured by the Vectrino 2 device, which works on the principle of the Doppler effect, allows us to observe the vertical distribution of velocities and turbulent characteristics of the flow. Measurements lasting 12 minutes were performed at different flow rates. The results of the processing of all measurements are presented graphically to facilitate the comparison of results for different flow rates.
