A 3D CIP-based numerical simulation of dam-break with obstacle
In this paper, a three-dimensional constrained interpolation profile (CIP)-based Cartesian grid model is proposed to accurately estimate impact loading time history of dam-break water with an obstaele.The model is based on the Navier-Stokes equations and the flow solver is solved by a CIP method.In order to track correctly complex three-dimensional nonlinear free surface flows, a more accurate VOF-type interface capturing scheme, the THINC/SW scheme, is adopted as the interface capturing method.A three-dimensional dam-break wave with a tall rectangular structure located downstream is considered.The velocities at a single point and the impact forces of the upstream surface and the downstream surface of the structure are computed by this model.The numerical solutions obtained with our CIP-based model have been compared with experimental results and a very satisfactory agreement is obtained in each cases.Thus, the conclusion is drew that this model is able to reappear complex three-dimensional nonlinear free surface flows and, much more than this, also able to obtain a precise and little oscillatory pressure field.
