  • Effect of the structure of backward orifices on the jet ...

    2020-9-25 · Self-propelled nozzle is a critical component of the radial jet drilling technology. Its backward orifice structure has a crucial influence on the propulsive force and the drilling performance. To improve the working performance of the nozzle, the numerical simulation model is built and verified by the experimental results of propulsive force. Then the theoretical model of the energy ...

    2017-4-10 · To obtain a suitable parameter window for the nozzle travel rate in jet ECM process, its effect on the machining quality index was investigated using both simulation and experiments, as shown in Fig. 12, Fig. 13. Fig. 12 exhibits top-view profiles of the grooves obtained using different nozzle travel rates: 250, 100, 50, 25 and 10 μm s −1.

    2010-2-1 · A drop forms as a result of the inertial pressure. This pressure equals to ρ v 2 / 2 in which, ρ is the density of liquid and v is velocity and balanced against the restraining pressure 2γ/r. γ is the surface tension and r is the radius of the deforming surface. By taking a ratio of these two pressures, Weber (We) number can be defined.

  • Effect of Nozzle Port Angle on Transient Flow and Surface ...

    2018-11-5 · The jet from the upward-angled nozzle port has more horizontal spread (3.38 deg) than the downward-ports jet (1.21 deg). Transient flow in the nozzle bottom region produces asymmetrical counter-rotating double swirling patterns at the port outlet, showing both clockwise and counter-clockwise flow with both port angles.
