摘要: ► A new set of macroscopic model equations is derived and developed. ► Interactions of dam-break wave and porous media are examined by present model. ► We examine the effects of different gate motions and porous media. ► Flow patterns are similar, if flows propagate for a sufficiently long period. ► Net force between flow and structure is greatly reduced if the structure is porous. A set of macroscopic model equations for describing the interaction of dam-break waves and porous media is presented. A mathematical model based on spatial averaging theory proposed by Slattery [1] is derived. The large eddy simulation turbulence model and the moving-solid algorithm are incorporated for observing the wave behavior within porous media. The model is validated using two-dimensional experimental data for dam-break wave interaction with porous structures [2], three-dimensional dam-break wave evolution [3,4] as well as impact force of dam-break wave on an impermeable vertical column [5]. Numerical experiments of three-dimensional dam-break waves impacting porous media are subsequently performed. The net force on the structure and the horizontal velocity on a fixed point are also discussed. 出版者: Kidlington: Elsevier Ltd 出版日期: 2012-10-01 出處: Advances in water resources, 2012-10, Vol.47, p.14-30 資源來源: ScienceDirect (Elsevier) Journals 版權: 2012 Elsevier Ltd 版權: 2015 INIST-CNRS 識別號: ISSN: 0309-1708 識別號: EISSN: 1872-9657 識別號: DOI: 10.1016/j.advwatres.2012.06.007 識別號: CODEN: AWREDI
