| 摘 要： | 超高速超空化水下航行体减阻新技术是目前最具前景的一种减阻方法,空泡形态稳定性及其尺度控制是决定其减阻效果的关键.在高速水洞中采用通气方式进行了超空化气体流量对空泡尺度的影响实验研究,得出了泄气率和超空泡形态调控的影响规律.基于相似方法和量纲理论获得了流量系数与空化数的定性与定量关系.所得结论对水下航行体超空泡水动力特性和非定常空泡控制技术的研究具有重要意义.

| Abstract: | The artificial supercavitating technology is one perspectively method of drag reduction for underwater vehicles. The significant problem of the darg reduction effect is the configuration stability and the dimensional control of the supereavity. The experimental investigation on ventilated supereavity was carried out in high speed water tunnel of NPU. The qualitatively and quantificational parameter relationship between the dimensionless ventialtion rate and the cavitation number which denotes the supereavitaty magnitude shape was presented by means of the similarity method and dimension theory. Some approximately regulate and control rules of the supereavity configuration by means of ventiahion rate were provided, |
