Abstract

V diplomskem delu je predstavljena uporaba programskega paketa Solidworks Flow Simulation pri analizi in določitvi tokovnih karakteristik ejektorja za medicinske namene, naprave, ki ustvari sesanje po Venturijevem principu, ter določitev vpliva gostote mreže na rezultate numerične simulacije. Na obravnavanem ejektorju so bile najprej narejene meritve pretoka in podtlaka, ki so služile primerjavi rezultatov z numerično simulacijo. Numerična simulacija je bila narejena za dva različna režima z drugačnim robnim pogojem, s prvim je bil izračunan pretok, z drugim pa podtlak. Za vsak režim so bile zmodelirane tri različno goste mreže. Z Richardsonovo ekstrapolacijo je bila izračunana numerična negotovost in s tem določen vpliv gostote mreže na rezultate simulacije. Uporabljeno računalniško orodje se je izkazalo za učinkovito pri reševanju inženirskih problemov s področja toka tekočin.

Secondary title: Determination of flow characteristics in medical ejector with numerical simulation
Secondary abstract: In this diploma thesis, Solidworks Flow Simulation software was used for analyzing the flow characteristics of ejector for medical purposes, device that generates vacuum on the Venturi effect, and determining the influence of different meshes on the results of numerical simulations. The main goal was to compare the results of numerical simulations of two different regimes with different boundary conditions with experimental results; therefore, measurements of flow rate and vacuum on ejector were performed. Three different meshes for each regime were made. To determine the discretization error Richardson extrapolation method was used. It was found that SolidWorks Flow Simulation is very useful for simulating different types of flows and for solving different engineering problems.
