摘要： A nozzle (10) comprising a through-hole (20) having an optional initial section (36) in fluid communication with the inlet opening (21) of the through-hole (20), a fluid shearing section (40) in fluid communication with the outlet opening (32) of the through-hole (20), and an optional transition region (38) in fluid communication with the initial section (36) and the fluid shearing section (40). The initial section (36) has a relatively constant cross-sectional shape along at least a 20% portion of its length, a shape that converges to the transition region (38), or both. The transition region (38) is disposed along the through-hole length, with a relatively uniform, diverging, converging, diverging and converging, or converging and diverging cross-sectional area along its length. The fluid shearing section (40) has an upstream end in fluid communication with the transition region (38), and a diverging cross- sectional shape along at least a 20% portion of its length that has a minor axis length and a major axis length.
