摘　　要：通过两种直径吃水比D/T=1.2和D/T=1.4分节驳顶推船队(2×2+T)模型的深水试验研究,给出了该种双隧道推船模型采用内、外旋向螺旋桨航行时推进性能的差别,并采用预旋流理论和流线示踪方法探讨了造成该差别的原因。This paper deals with the model test of integrated pushboat barges(2×2+T) and gives the differ ences in propulsive performance between the inward and outward turning of screw propellers.The pushboat model has a twin tunnel stern. According to the ratios of screw diameter to ship draft, 1.2 and 1.4, the tests were carried out. By applying the theory of pre-swirling and the method for flow tracking,the reasons of those differences are discussed.
