为提高离心式高效喷溅装置的布水均匀性，采用欧拉(Eulerian)多相流模型和重整规划群（RNG）k-ε湍流模型对离心式高效喷溅装置的水力特性进行了三维数值模拟,将其模拟的溅洒情况与试验情况进行了对比，验证了模型的正确性。并用此方法研究了离心式喷溅装置在3种水头和4种转速下的水力特性，结果表明其能在较广的水头和转速范围下均能实现均匀布水，且一定范围内提高水头和降低转速可以提高布水均匀性，提出离心式高效喷溅装置的建议工作转速为60r/min~120 r/min。

In order to improve the uniformity of water distribution of efficient centrifugal spray nozzle, the Eulerian model, one of multiphase flow, and the RNG turbulence model were chosen in there-dimensional numerical simulation to investigate the hydraulic characteristics of efficient centrifugal spray nozzle. Comparison of numerical simulation results with experimental results verified the correctness of the model. The hydraulic characteristics of efficient centrifugal spray nozzle were comparatively analyzed under three head conditions and four speed conditions with this numerical simulation method. The results showed that it could achieve uniform water distribution in a wide head range and a wide speed range. The uniformity of water distribution of efficient centrifugal spray nozzle could be improved by raising the head and reducing the speed in a certain range. Accordingly, the recommended working speed range of the efficient centrifugal spray nozzle was 60 r/min~120 r/min.
