中文摘要：

介绍了作者发明的一种新型的窄通道高速拖曳水槽,对不同头型的方形及圆形截面的模型进行了高速拖曳实验,实验模型的最大速度可达约18m/s。通过高速摄影仪进行实时记录,对模型的运动特性以及空化尾迹特性进行了研究。实验结果显示,圆形截面模型的速度曲线更加稳定;对于方形截面的模型,头型为90°角的模型加速性能最好。

英文摘要：

A new type of narrow-channel high-speed towing tank has been developed.The test models with different head and cross-sectional shapes were examined in the tank.The maximum velocity of the test models can reach about 18m/s.Using high-speed photography,the motion characteristics of the test models and the cavitating wakes behind the models were studied,and two groups of test models with square and circular cross-sectional areas were applied.It is concluded that the models with circular cross-section give more stable velocity curves.The model with 90° head taper angle gives the best acceleration behavior among the models with square cross-section.
