T-junction mixing laboratory experiment

U radu je dan pregled eksperimentalnog mjerenja miješanja u dvostrukom T-spoju s naglaskom na praćenje onećišćenja kroz spoj. Razmotrena je važnost T-spoja kao najzastupljenijeg naćina povezivanja cjevovoda u industriji i distribucijskoj vodovodnoj mreži. Dan je pregled matematičkih modela koji opisuju miješanje. Detaljno je opisana metodologija eksperimentalnog mjerenja, bitnih fizikalnih veličina, razvoj i slaganje opreme za mjerenje, te postupak mjerenja.This thesis gives an overview of experimental measuring of mixing in double T-junctions, with focus on measuring contaminant concentrations. Importance of T-junctions as a predominant way of connecting pipelines in the industry and water distribution network is reviewed. Mathematical models that describe mixing are overviewed. Detailed description of the methodology of experimental measurements, physical characteristics, research and development of measuring equipment, and the process of measuring itself is given
