1. 36. Design of Experiment Based on Full Factorial CFD Spray Modelling

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Olle Faritzon; [2023]
   Nyckelord :CFD; spray; liquid; injection; DoE; Design of Experiment; fuel spray; Propane; LPG; OpenFOAM; Experiment; Fluid dynamics; maritime shipping; engine; Technology and Engineering;

   Sammanfattning : Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. LÄS MER
