Droplet-laden laminar flames

The strained laminar flame is a paradigm in understanding combustion. But what about cases in which the flame contains droplets? We have started a series of experiments to determine how the presence rate of droplets affects the local flame burning rate and structure.

Below are preliminary studies of acetone-methane laminar impinging flames flames with different size droplets at the same equivalence ratio. The flames show markedly different appearance as the droplets increase in size.

Reference flame velocities measured with PIV, as a function of strain rate, equivalence ratio and droplet sizes.
