Abstract:V diplomskem delu smo obravnavali tok vode preko prelivne ovire v odprtem hidravličnem kanalu. Numerično simulacijo toka smo izvedli na podlagi predhodno pridobljenih eksperimentalnih podatkov meritev PIV ter rezultate primerjali z izmerjenim hitrostnim poljem. Numerični model je temeljil na geometriji laboratorijskega kanala, tok smo analizirali pri dveh različnih konstantnih pretokih. Namen naloge je bil preveriti, kako dobro numerična simulacija opiše tokovne razmere v merilni ravnini in kako se rezultati ujemajo z eksperimentalnimi meritvami. Primerjava je pokazala, da numerični model uspešno prikaže osnovne značilnosti toka preko ovire, predvsem nastanek recirkulacijskega območja in porazdelitev hitrosti. Numerična simulacija se je izkazala kot ustrezno orodje za analizo toka in dopolnitev eksperimentalnih raziskav.

Title:Comparison of Numerical and Experimental Analysis of Water Flow over an Obstacle
Abstract:This thesis investigates the flow of water over a weir in an open hydraulic channel. The numerical simulation was performed based on previously obtained experimental PIV measurement data, and the results were compared with the measured velocity field. The numerical model was based on the geometry of the laboratory channel and the flow was analyzed at two different constant flow rates. The aim of the study was to evaluate how accurately the numerical simulation describes the flow conditions in the measurement plane and the agreement between the results and the experimental data. The comparison showed that the numerical model successfully captures the key flow characteristics over the weir, especially the formation of the recirculation zone and the velocity distribution. The numerical simulation proved to be an effective tool for flow analysis and for supporting experimental investigations.
Keywords:numerical simulation, CFD, PIV, open channel flow
