Abstract:Numerično modeliranje in simuliranje je eno izmed najboljših orodij za dopolnitev eksperimentalnega preučevanja curka kapljevin in daje zelo obetavne rezultate za izboljšanje razumevanja kompleksne narave curka. Namen magistrskega dela je bila numerična analiza vpliva več-sestavinskega goriva na uparjanje, dolžino vbrizga in razpršitev kapljic goriva ter primerjava teh rezultatov z eno-sestavinskim gorivom. S tem delom sta bili opravljeni kalibracija in validacija Lagrangeevega več-faznega modula programskega paketa FIRE. Iz dobljenih rezultatov sklepamo, da dodajanje različnih koncentracij etanola bencinu, nima vidnega vpliva na obnašanje procesa vbrizgavanja goriva. Opravljena kalibracija modula daje komplet nastavitev, katere je kasneje mogoče uporabiti pri simulacijah celotnega motorskega cikla.

Title:Spray bomb multi-component CFD simulation of gasoline fuel
Abstract:Numerical modeling and simulation is one of the best tools to complement the experimental study of fluid spray and provide very promising results for a better understanding of the complex nature of the spray. The purpose of the master thesis was numerical analysis of the impact of multi-component fuel on vaporization, penetration length, atomization of injected fuel and to compare these results with one-component fuel. Within this work calibration and validation of Lagrangian multi-phase module of the software package FIRE was carried out. From the obtained results can be seen, that ethanol blending of gasoline at different concentrations, has no apparent effect on the behavior of the process of fuel injection. The calibration of the module provides a set of settings, which later can be used to simulate the entire engine cycle.
Keywords:spray simulation, fuel injection, multi-component fuel, Lagrangian multi-phase module, numerical simulations, spray breakup, evaporation, penetration length, E15, E50, E85
