Abstract
The article presents results of experimental investigations of common-rail Diesel jet impingement on highly porous, open cell structures. A model describing characteristic phases of Diesel jet interaction with a porous structure is presented in the article. Phase A represents outlet from the nozzle and free jet formation; phase B contains jet interaction with the porous medium interface; phase C relates to liquid distribution throughout the porous medium volume; and phase D describes liquid leaving the porous medium volume. Phases B and D can significantly be reduced or eliminated owing to the pore density, impingement velocity, and porous medium thickness. Special attention is focused on the spatial distribution of the jet throughout the porous medium volume, giving rise to a very effective homogenization effect, and under hot conditions, also for vaporization of liquid. A multijet splitting has been defined to explain destruction and spatial distribution of a free jet momentum inside the porous medium structure. The effect of injection parameters (especially injection pressure) and pore density (pore size) is also investigated in this article.
