Abstract
U ovom radu obrađujemo eksperimentalne profile brzina pri rubnim uvjetima Q1d2. Eksperimenti se odvijaju u sklopu projekta R3PEAT čija se motivacija istraživanja temelji na analizi procesa podlokavanja u blizini riprap zaštite oko stupova mostova. Obuhvaćaju mjerenje profila brzina pri protoku Q1 (30 l/s) i dubini toka d2 (20 cm). Rezultate brzine strujanja vode u stvarnom vremenu u hidrauličkom kanalu smo dobili pomoću kontinuiranog mjerenja sa visoko frekventnim ADVP uređajem. Koristili smo različite slučajeve protoka (Q1 = 5 l/s; Q2 = 10 l/s; Q3 = 15 l/s; Q4 = 20 l/s; Q5 = 25 l/s; Q6 = 30 1/s) za uspoređivanje rezultata i analize promjena u koritu. Cilj ovog rada je analizirati profile brzina (komponente u, v, w) duž presjeka za svaki slučaj protoka te pomoću izmjerenih brzina prikazati hidrauličke karakteristike (Reynoldsovo naprezanje i turbulentnu kinetičku energiju) i njihove utjecaje na eroziju korita.
Abstract (english)
In this work, we investigate experimental velocity profiles under boundary conditions Q1d2. The experiments are part of the R3PEAT project, which aims to analyze the scouring process near riprap protection around bridge piers, We measure velocity profiles under flow rate Q1 (30 L/s) and flow depth d2 (20 cm). Real-time water flow velocity results in the hydraulic channel were obtained using continuous measurements with a high-frequency ADVP device. We used various flow cases (Q1 = 5 L/s; Q2 = 10 L/s; Q3 = 15 L/s; Q4 = 20 L/s; Q5 = 25 L/s; Q6 = 30 L/s) to compare results and analyze changes in the channel. The objective of this work is to analyze the velocity profiles (components u, v, w) along the cross-section for each case of flow and demonstrate the turbulence characteristics (Reynolds stress and turbulent kinetic energy) and their impacts on channel erosion using measured velocities.
