| 摘 要： | The characteristics of the impinging pressure at the jet equipment where the maximum jet velocity can reach 50m/s were studied. By comparing the impinging pressure with the one measured at the low velocity conditions, two conclusions of the scale effect are drawn： firstly, the velocity attenuation degree is smaller than that of low velocity jet, and secondly, the relative impinging width is narrower than that of low-velocity jet. The reasons of the scale effect of the impinging pressure were elucidated through numerical simulation.

By comparing the impinging pres sure with the one measured at the low velocity conditions, two conclusions of th e scale effect are drawn: firstly, the velocity attenuation degree is smaller th an that of low-velocity jet, and secondly, the relative impinging wid th is narrower than that of low-velocity jet. The reasons of the scale effect o f the impinging pressure were elucidated through numerical simulation. |
