Modellierung von Einspritzvorgängen in Motoren (Modeling of Injection Processes in Internal Combustion Engines)
- The aim of this work is the analysis of characteristic properties of fuel jets in internal combustion engines for steady and transient spray velocities by means of CFD. The simulations were done using DNS. The used software is Gerris. Calculations with different Reynolds numbers, Weber numbers and density ratios were done. The adaptations of an already existing simulation file included the implementation of necessary output capabilities. The analysis of obtained data was done by previously created macros. The obtained non-dimensional results give information on penetration, number of droplets, SMD and droplets size distribution. One calculation was compared to experimental data.
