  • Characteristics of Unsteady Flow Behaviour in the Open Channel with Rectangular Dead Zone

この論文をさがす

説明

The unsteady flow behaviour in the open channel with rectangular dead zone is investigated by both the numerical analysis and the laboratory tests. It is pointed out that the temporal velocity and depth variations at the interface between the main flow and the rectangular dead zone can be decomposed into the three components of (1) the shear layer instability, (2) the seiche and (3) the long period oscillation with twice the period of the seiche. The last component is caused by the alternate pattern of vortex impinging to the downstream corner. It is shown that the unsteady characteristics of the flow are well reproduced numerically by means of 2D-plane open channel flow equations
