Abstract
The characteristics of a fuel spray atomized by a steam jet were studied using the method of shadow photography. The studied method of forming a two-phase flow for dispersing liquid fuel allows application of a wide range of hydrocarbons and increases the service life of the combustion equipment due to the absence of fuel spraying nozzles. Using a long-focus macroscopic lens, the dispersed composition of spent engine oil was measured at various fuel supply frequencies: 10, 25, and 40 Hz. The dispersed phase velocity was determined using the PIV-algorithms; it amounted to 60 m/s for all studied regimes. It is shown that the frequency of liquid fuel supply does not affect the size and velocity of the formed fuel droplets.
