摘要
研究了制约直升机-舰动态配合性能的首要原因——直升机的载舰在海上风场、舰面特殊结构、舰艇运动等因素作用下形成的非定常舰面紊流场。在总结早期直升机-舰动态配合试验研究特点的基础上,分析了舰面流场海上实测试验的方法及其发展;针对舰面流场模拟普遍采用的CFD技术,分析了舰面流场CFD仿真的发展过程及现状。评价了新型CFD方法——DES在处理大分离涡外流方面的优势,指出了DES在舰面流场仿真领域的光明前景。
To study the main factor restraining the dynamic interface performance of helicopter and ship-an unsteady flow field formed on the helicopter carrier by sea breeze, special structure of the ship and ship movement. Based on the fea-ture of dynamic interface test of helicopter and ship in early stage, the methods of shipboard flow measurement as well as its development were analyzed. As for the CFD technique-usually used in flow simulation, its development and status were discussed. The advantage of DES, a new method of CFD, in handling Large-separation external flow was introduced and its bright perspective in simulation of shipboard flow was pointed out.
