Simulacija tokovnih razmer v pljučih

diplomsko delo

Jakob Roter (Author), Jure Ravnik (Mentor)

Abstract

V diplomski nalogi je predstavljena numerična analiza tokovnih razmer v pljučih. Opisano je teoretično ozadje simulacij tokovnih razmer in izpeljava glavnih enačb za ohranitev mase in gibalne količine. Prav tako je opisana teorija izbranega turbulentnega modela k-ω SST. Za potrebe numerične simulacije so bile narejene štiri različne računske mreže: ena tetraedrična in tri poliedrične. Na podlagi primerjave rezultatov tokovnih razmer različnih računskih mrež, je med vsemi bila izbrana najboljša računska mreža. To računsko mrežo smo nato primerjali z rezultati iz članka Koullapis in sod. [1] in tako validirali lastno numerično simulacijo.

Secondary title:	Flow simulation in lungs
Secondary abstract:	In the bachelor’s thesis we examine numerical analysis of air flow through lungs. We describe theoretical background of flow simulations by deriving main equations for mass and moment continuum. Theory background of k-ω SST turbulence model is also presented. There were four different meshes made for the purpose of numerical analysis: one that has tetrahedral cells and three with polyhedral cells. Based on result comparison between four meshes, best one was selected and compared to the results of different numerical method studies presented in Koullapis and co. [1].
