摘　　要：为了提升底部造流水动力试验装置测试区域流态,针对可调角度导叶组进行多工况计算流体力学(CFD)模拟对比优化。结果表明:在8 m、6 m和4 m等不同水深工况下,调节进水端导叶组角度分别为50°、40°和30°,出水端导叶组角度统一为30°时,测试区可形成平均流速为1m/s、均匀度为±15%的水流,且减少了回水端管路中涡流区的存在。因此,通过可调角度导流措施可使得底部造流系统在不影响大水深造波的前提下在测试区和回水管道中形成较为均匀的水流分布。In order to improve the flow pattern in the test area of test device with bottom current generation,multi-condition computational fluid dynamics(CFD)simulations are conducted on the adjustable-angle guide vane group for optimization and comparison.The results show that under different water depth conditions of 8 m,6 m and 4 m,by adjusting the angle of the guide vane group at the water inlet to 50°,40°and 30°respectively,and maintaining the angle of the guide vane group at the water outlet at 30°,the test area can generate a water flow with an average velocity of 1 m/s and a uniformity of±15%,while reducing the presence of vortex regions in the return pipe system.Therefore,by using adjustable angle deflection measures,the bottom flow generation system can create a relatively uniform water flow distribution in the test area and the return channel without affecting wave generation in deep water conditions.
