Paper Title:
Research on Structural Parameters of Conical Nozzle
  Abstract

Inner flow field numerical simulation model of conical nozzle was established. The relationship between conical nozzle structural parameters and its performance were obtained with simulation research. Simulation results show that the maximum outlet velocity of conical nozzle and the fluctuation range of radial velocity at outlet are determined by its convergence angle α and slenderness ratio Cp. With the increasing of α, the maximum outlet velocity of nozzle is increased at first and then reduced. When α is small, the fluctuation range of radial velocity at outlet is minute. When α is big, the fluctuation range of radial velocity at outlet is dramatic. With the increasing of Cp, the maximum outlet velocity of nozzle is increased at first and then reduced. When Cp is small, the fluctuation range of radial velocity at outlet is obvious. When Cp is big, the fluctuation range of radial velocity at outlet is minute. The optimal structural parameters of the nozzle are α = 40°, Cp =30°. Experiments of conical nozzle performance with different α were carried out. Experimental results show that ejection range of water jet is maximal when α = 40°.
