Content
To study the characteristics of flow velocity and particle diameters in large angle conical spray proposed for hot-premixed combustion type Diesel engines, steady and unsteady conical sprays have been analyzed using laser Doppler anemometry (LDA), and phase Doppler anemometry (PDA). Three injection pressures were used in steady experiments. In unsteady experiments, the frequency of injection was 20.7 Hz and the amount of injection fuel was 10.3 mg or 25.6 mg in each cycle. Distributions of bulk velocity, fluctuation intensity of the velocity, air entrainment rate, Sauter mean diameter of particles and correlation between particle diameter and velocity of the spray were obtained.
