NUMERICAL STUDY ON TURBULENT FLOWS AROUND THE OGEE VALVE OF THREE GORGES SHIP LOCK

摘要

This paper concerns with the numerical simulation method of turbulent flows around the ogee valve of Three Gorges ship lock. At first the calculating domain is divided into several sub-domains by multi-block matching method, and in each sub-domain structured orthogonal grids are generated by T&M and Hilgenstock method, finally the turbulent flow field is simulated by Hybrid Finite Analytic Method (HFAM) with the standard k- e model. The numerical results are in agreement with two-component laser-Doppler measurements.
