Boundary Conditions - Direct Injecion for Cat-Heating Operating Points
For the investigations, the engine was operated at a speed of 1500 rpm and an intake pressure of 0.95 bar. Starting from the base operating point with early injection and... -
Flow Field - Direct Injecion for Cat-Heating Operating Points
PIV was used to measure the flow fields and their velocities. A double-pulsed high-speed Nd:YVO4 laser (Edgewave IS4II-DE, 532 nm) was formed into a laser cut with several... -
Flame PDF - Direct Injecion for Cat-Heating Operating Points
The PIV raw images were used for flame detection and therefore have the same optical structure. Only the relevant parts of the cycles from the ignition point onwards were... -
Spray_Average - Direct Injecion for Cat-Heating Operating Points
The spray was visualized using high-speed images of the Mie scattering of the fuel droplets. The liquid fuel was illuminated with a volumetrically expanded laser beam through... -
Multicycle LES simulation of Darmstadt Engine running in motored condition
Multicycle LES simulation of the Darmstadt Engine running in motored condition. Operating point A (800 rpm, 0.95 intake pressure). Simulation is performed with OpenFOAM and the...
