摘要：

This study studies the propagation of dam-break flow on a horizontal dry bed with a lifting gate taken into consideration. The focus is placed on the development of an accurate and efficient gas/liquid/solid interaction numerical model, in which the free-surface evolution is captured using the Mass-Preserving Level Set (MPLS) method and gate motion is handled using the direct-forcing Immersed Boundary (IB) method. This numerical model is validated by experimental results in terms of free-surface profile, wave front location and water column height. Furthermore, emphasis is placed on computational costs for dam-break flow by using the present MPLS/IB model and the Coupled Level Set and Volume of Fluid (CLSVOF)/IB model proposed in Ref. [Commun Nonlinear Sci Numer Simulat 79 (2019) 104934].
