Description
Summary:The applicability of the commercial CFD-Program STAR-CD for hydraulic problems was evaluated by the pressure distribution downstream of an opening lock valve.Various valve operation speeds were modeled. This gave information about the possibility to simulate the flow around and induced by moving structures. Results of the numerical simulations were compared with results of physical model tests. Differences between measured and computed pressures in the unsteady flow were in a range of 1-2 percent, although the maximum differences in flow rates were about 15 percent.
