Description
  • Publikovaný článek se zabývá problematikou vizualizace 2-D proudění využitím ultrazvukové dopplerovské anemometrie (UDA). Proudové pole bylo měřeno v podélné rovině symetrie hydraulického modelu z plexiskla nově navrhované odlehčovací komory (OK) pomocí ultrazvukového rychlostního profileru. Experimenty byly zaměřeny na i) optimalizaci geometrie OK a na b) získání dat pro kalibraci a verifikace 3-D matematického CFD modelu. Výsledky ukazují na velký potenciál UDA metod v kombinaci s numerickou analýzou dat zobrazovat 2-D proudění. Navíc byla optimalizována geometrie OK vzhledem k gravitační separace nerozpuštěných látek a plovoucích nečistot. Srovnání experimentálních dat a CFD simulací vykazují ucházející shodu. (cs)
  • Presented paper deals with 2D flow visualization using Ultrasonic Doppler Method (UDM). The flow patterns in the axes of plane symmetry of designed combined sewer overflow (CSO) were measured on the hydraulic model made of plexiglass using Ultrasonic Velocity Profile (UVP) Monitor. The experiments were focused on both, the optimalization of CSO geometry and the verification of the 3D CFD model. The results show great potential of the UDM in combination with numerical analysis to visualize 2D flow field. Moreover, the optimal geometrical configuration with respect to the gravitational separation of suspended solids content and separation of floatable solids was found as well. The comparison between experimental values and CFD simulations introduces sufficient agreement.
