The Spray Angle Improvement of Single Inlet Pressure Swirl Atomizer Using Partial Structure Modifying
This paper analyzed the velocity field of the section between outlet orifice and the conical swirl chamber with a kind of single inlet pressure atomizer using CFD (Computational Fluid Dynamics) method. A method of modifying the outlet orifice position referring to the swirl chamber in order to improve the spray angle and its homogeneity is proposed. The result of the experiments shows that it is a feasible method to improve the quality of this kind of atomizer.
