| 摘 要： | 形成通气超空泡所需的通气量是设计试验的一个重要参数,适当的通气量才能形成形态可控且减阻的理想超空泡.表征通气量的无量纲参数是通气率,形成超空泡的最小通气率称为临界通气率.在可连续通气水洞中对航行体缩比模型进行了通气超空泡试验,通过改变水洞工作段的来流速度和压力、模型比例和空化器等因素,获得了一系列不同形态的通气超空泡,分析了影响通气超空泡临界通气率的因素.

| Abstract: | Ventilation is one of the important technologies in the field of supercavity,and a perfect ventilated supercavity with shape controllable and drag reducible could be gotten only with suitable volumetric flow rate of gas.Ventilation coefficient is the nondimensional coordinates of the flow rate,and the critical ventilation coefficient is corresponded the minimal flow rate to get supercavity.A series of experiments were conducted to examine ventilated cavity physics.With changing the velocity and pressure of ... |
