【摘要】 通气空泡的形态直接影响水下航行体的航行性能,文章采用数值分析方法对二维典型平头型航行体在不同通气孔位置、通气流量、通气角度条件下通气空泡/超空泡的形成,以及有侧壁干扰作用下的通气空泡形态进行分析。研究结果表明:上述各通气参数的合理配置对稳定超空泡的形成至关重要,且必须对洞壁影响下的试验结果进行修正。更多还原

【Abstract】 Flow characteristics of underwater vehicles are directly related to its cavity profile,which is affect by many factors.In this paper,ventilated and super-cavities around a typical two-dimensional blunt-type model are analyzed at different ventilated locations,flow-rate and angle conditions.The lateral wall interference is also performed.The results indicate that the above parameters should be adjusted properly to improve the stability of ventilated cavity formation,and the experiment results need to be amended under the intense wall interference conditions.更多还原
