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 C_p. 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 C_p, the maximum outlet velocity of nozzle is increased at first and then reduced. When C_p is small, the fluctuation range of radial velocity at outlet is obvious. When C_p is big, the fluctuation range of radial velocity at outlet is minute. The optimal structural parameters of the nozzle are α = 40°, C_p =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°.
