Abstract:

The collision behavior of droplets of low surface tension fuels simulating near-critical droplet collision in high-pressure engines, and of droplets of dissimilar fluids simulating the atomization of unlike reactants, were experimentally studied. Results showed that the low-surface tension fuels do not readily disintegrate, while the dissimilar fuel droplets can actually merge. These collision dynamics were also computationally simulated using the techniques of front tracking and molecular dynamics. The computer algorithms developed for droplet collision were also extended to simulate the dynamics of wrinkled flames in complex flows, including flame-vortex interaction and the development of the Landau-Darrieus cells.
