Simulation Study of Nozzle in Fire Engine Based on Fluent

摘要

Focus on the technology and requirements of nozzle in fire engine to optimize the ability of blasting of nozzle, this paper built the model of fluid in nozzle, and simulation studied based on Fluent. This paper analysis the stage of nozzle, contraction angle, size of entrance and slenderness ratio as the influencing factors, supplied the reliable theoretical foundation for the design and structural improvement of nozzle in fire engine.
