Introduction In the plate strip rolling process,due to high temperature oxidation,the oxide layer formed on the surface of plate strip.Descaling effect of Iron and steel company is generally poor at home and abroad,resulting banded oxide skin in surface of steel strip, oxide pock, oxide hang and other surface defects[1,2].This issue has become a swimming forever hidden pain in the head of steel company[3,4].Therefore,getting Jet flow field of the nozzle and affect factors of the external flow, is an essential problem to be solved.In this paper, using the finite element method for fluid dynamics simulation and Fluent and Gambit software for finite element numerical solution to explore jet flow field and the influence factors.
Experimental materials and methods The simulation of high-pressure water jet flow field of nozzle is the study of two-phase distribution of gas-liquid in the standard atmospheric pressure,Therefore, Selected calculation model is pressure-velocity coupling model.Figure 1(a) is Gas-liquid two-dimensional model of external flow.model specific parameters are as follows:Entrance speed:200m/ s;Entrance pressure:20MPa;Exit pressure:0.101 MPa (1atm),the unit of exit pressure: Kg/s;Select the triangle mesh,equidistant division.
Figure 3 Velocity vectorof flow field Analysis of velocity change Figure 4 shows the velocity curve of the jet beam along the axis.it can see from the figure, jet velocity remained unchanged in the core area of the jet.When the jet into the transition zone, the jet velocity began to decrease,When the jet nozzle to leave a distance of about 220mm,the jet velocity decreases significantly, the slope of attenuation curve suddenly plunged, here is the basic segment and the dissipation of the line segment, which is the maximum target distance.Therefore,the best target should be near here from this theory.According to the formula-type fluid,it can be calculated that Lopt about 220.2mm[5],that are very close simulation values,so it can be convinced that simulatere result is credible in some extent.
