| Abstract: | Using the gambit of lead processing software CFD to establish the visual modeling,the speed of fan-shaped nozzle of high pressure water jet was solved by fluent.According to the velocity distribution cloud to analyze the main factors of influence of fan-shaped nozzle high pressure water jet speed.The results showed that export blind side length and relative offset notch of the fan-shaped nozzle influence the internal flow field more,length of cylinder and notch half-width influence the internal flow field little.The simulation results provided theoretical basis for the design of fan-shaped nozzles and had some guiding significance to the actual projects. |
