Pressure swirl nozzles equipped with a convex deflection orifice are used for enlargement of the spray angle up to 180 degrees and smaller drop sizes are expected from that operation. The sheet deflection behavior is investigated quantitatively by spray angle measurements for a wide range of operating conditions and nozzles geometries. To achieve proper deflection, the radius of the trumpet contour has to be adapted to the flow conditions generated upstream. Besides the spray angle, the sheet velocity is also known to have a major influence on the drop size and has been measured as compared to common nozzle types. For the deflected sheet, the velocity coefficient may go down to phi approximate to 0.7 compared to plain orifice geometries with phi > 0.9 depending on swirl ratio and viscosity. Finally, the drop size depending on the deflection geometry is measured by laser diffraction and opposed results were found depending on the operating conditions, especially on the viscosity. For low viscosity disturbances were amplified by the deflection orifice and lead to considerably lower breakup length.
