BOUNDARY-LAYER CHARACTERISTICS OF A SWIRL ATOMIZER
要約
The Bloor and Ingham analysis for the boundary-layer flow above aflat disk has been used for the case of a swirling flow in a conical nozzle, and the proportion of the fluid that enters the orifice through the boundary layer has been estimated. Comparisons of these results with measured flow rates indicate that the flow through the boundary layer represents almost all the outflow from a swirl atomizer over a wide range of injection pressures when the radius of the orifice and the radius of the inlet groove are relatively small compared to the radius of the swirl chamber, but that it may be neglected for small injection pressures and large radii of the orifice and the inlet groove.
