带附体的门桥水动力性能试验研究

Experimental investigation on hydrodynamicperformances of appendaged raft

为了改善门桥的水动力性能,增设了对近壁面流场进行流动控制的水翼.船模水池中的模型拖曳试验表明,尽管水翼会增加门桥的水阻力,但只要合理地设计水翼的翼型、攻角和安装位置,可以改善和提高门桥水动力性能.

In order to improve hydrodynamic performance of a ferrying raft, two hydrofoils are set in the raft＇s wetted hull, which will control the flow field near the wall surface. Experimental data from the towing tank tests show that the hydrofoils give more water-drags on the raft＇s hull, and that the hydrodynamic performance of a ferrying raft will be improved by rational designs of the hydrofoils＇ profile, angles of attack as well as the position of hydrofoil on the hull.
