摘要：
This paper reports on the contraction, velocity and discharge coefficients of cone-capillary, streamline and capillary-cone nozzles under water reservoir pressure range of 30-120 atm, obtained depending on numerical simulation. The contraction, velocity and discharge coefficients of hydroentangling nozzles are slightly affected by the water reservoir pressure, which are mainly determined by nozzle configuration.
