| Abstract: |
| Slinger is a type of rotary atomizer wherein spray spatial distribution varies with the rotary speed and mass flowrate. The spray parameters at a series of locations in the radial direction of the slinger were measured and the parameters of the location where the spray Sauter Mean Diameter (SMD) corresponds to the smallest were selected to be analyzed. The results indicated that at a specific mass flowrate, an optimum diameter exists for the orifice, in which the orifice’s spray corresponds to the smallest and most uniform. Increases in the mass flowrate increase the optimum diameter. Further, the spray from the circular orifice is more uniform compared with that from the slot orifice with the same circumference. When the length of the orifice increases, the spray becomes larger but more uniform. The liquid regime in the orifice affects primary atomization of the liquid, significantly affecting the spray SMD and uniformity. |
