摘要
关于超空泡流控制的研究是超空泡流研究领域里的难点和热点问题,它对实现超空泡航行体的稳定性和机动性具有重大意义。文章根据Savchenko提出的四种超空泡航行体稳定运动模式,提出了一种吸气控制超空泡流的方法。基于这种方法,给出了几种具体控制策略及其数值方法,并数值分析了在每个控制策略中流动和控制参数对超空泡流的影响。通过数值结果的比较分析,提出了一个更合理的吸气控制方法。该研究在一定程度上为实现超空泡航行体的稳定性和可控性提供了技术指导。
Research on control of supercavitating flows is one of the difficult and hot spots in the field of supercavitating flows and is also of great significance to keep the stability of supercavitating body and realize its maneuverability. An thought about suction gas control is put forward for ventilat-ed supercavity, considering the four stable motion patterns of supercavitating body proposed by Savchenko, and then according to the thought, several suction gas control schemes and the corre-sponding numerical method are proposed. Respectively based on these control schemes and the method, simulations of ventilated supercavitating flows are carried out to analyze influences of flow and control parameters on the flows. Finally, a more reasonable suction gas control scheme is sug-gested and is also confirmed by comparative analysis method according to numerical results. Research results provide technical guidance to realize the stability and controllability of supercavitating bod-ies to some extent.
