【Abstract】 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.更多还原
