Abstract

A novel self-excited oscillation spraying blade has been designed and the geometric model of the conical surface and rectangular surface self-excited oscillation spraying blade have been established. The flow field distribution of novel spraying blade has been obtained by finite element analysis, simulation results show that: the velocity is reverse close to both sides of the self-excited oscillation chamber, and the recirculation zone has been produced. From the lower spraying nozzle to the exit area of the oscillation chamber, the fluid speed is longitudinal symmetric distributed while the maximum speed appears at the junction of the lower spraying nozzle and collision wall, and the energy no loss after fluid through the oscillation chamber. Velocity distribution at the edge of conical surface self-excited oscillation spraying blade is more stable and uniform than rectangular surface self-excited oscillation spraying blade, the spraying area of the novel spraying blade can be increased, and the spraying atomization effect is greatly improved.
