Can combustible liquid aerosols lead to deflagrations?

Combustible liquid aerosols can indeed lead to deflagrations due to their ability to generate a flammable mixture when dispersed in the air. When these aerosols are suspended in a gaseous medium, they create fine droplets that have a larger surface area compared to bulk liquid. This increased surface area enhances the potential for rapid evaporation and subsequent combustion.

When the aerosolized droplets mix with air in the right proportion, they can form a flammable mixture that, when ignited, reacts quickly but typically at subsonic speeds—characteristic of deflagration. This combustion process can occur at lower energy thresholds than those required for bulk liquids due to the more efficient mixing and larger surface area of the dispersed liquid.

Understanding the role of temperature and pressure is essential as they influence the behavior of aerosols during a combustion event. However, aerosols that are combustible under the right conditions will invariably lead to deflagrative reactions when an ignition source is present.
