Abstract: | The physics of the impingement process of small hydrocarbon droplets is mostly unknown due to the difficulties of obtaining experimental data. In this publication, the impingement of small isooctane droplets on a hot piston surface is studied. The emphasis was put on the image-based investigation of the process of successive impingements and its influence on secondary droplet formation. The diameter and velocity of the secondary droplets were found to depend on the wall temperature and impingement frequency. Thus, the temporal interaction has a significant influence on the secondary droplet characteristics. |
