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.
