摘　　要：本文讨论了如何用分块耦合技术生成网格疏密状况和正交性能较好的网格 ,并用标准 k-ε模式模拟了三峡永久船闸反向弧形阀周围的紊流场。激光测试结果表明 ,计算结果与激光测速值吻合得较好。The multi-block matching method was discussed for solving complicated 2-D incompressible viscous flow in this paper. And the combination of T&M method and Hilgenstock method was proposed for generating good quality grid systems. Finally, the turbulent flow field around the valve of the Three gorges ship lock is simulated by the shandard k-ε m odel. LDV measurements show that the calculated results are in good agreement wi th the experimental data.
