embodiment 1
[0061]As shown in FIGS. 1(a)-1(d), a current injection nozzle structure has a cylindrical nozzle as shown in FIG. 1(a), a conical nozzle as shown in FIG. 1(b), a conical column-shaped nozzle as shown in FIG. 1(c) and a conical column diverging nozzle as shown in FIG. 1(d). The nozzle has relatively high requirements for velocity distribution and turbulence intensity of jet. The design of the nozzle requires that the jet velocity is relatively uniform, a velocity gradient is not easy to be too large, the turbulence intensity of the jet is low, the jet is not easy to have relatively large fluctuations, the concentration distribution of droplets at a nozzle outlet is uniform, and a concentration gradient of the jet is not easy to be too large. According to research experience of relevant workers, under the same inlet and outlet conditions, in velocity distribution, the velocity distribution at an outlet of the cylindrical nozzle is the most uneven, the central velocity distribution is ...
