两种不同结构的消防炮性能对比分析

The Performance Comparative Studyon Two Different Structure of Fire Monitor

在相同参数条件下,分别对串、并联结构消防炮流道引起的压降及喷嘴出口速度进行分析计算,并用FLUENT和Simulink对这两种不同结构消防炮的压力场和射流轨迹进行仿真分析。在不同流量下,分别对两种结构消防炮的压降和射程进行对比研究。通过综合比较得到并联结构比串联结构消防炮在降低压降、提高消防炮射程等方面具有优越的性能,为设计开发大流量、远射程、高能效的并联结构消防炮提供理论依据。

The pressure drop and outlet flow velocity of series and parallel structure fire monitor are calculated and compared under the condition of same performance parameters. Pressure field is simulated by using FLUENT and jet trajectory is simula- ted by using Simulink. Finally, the two structure fire monitor＇s pressure drop and jet trajectory are studied and compared un- der the condition of different flow. Through comprehensive comparison, parallel structure fire monitor is more superior per- formance than series structure fire monitor in terms of reducing energy consumption and increasing the firing range, which pro- vides theoretical basis for designing and developing large flow, long-range, energy-efficient parallel structure fire monitor.
