CFD Simulations of the Propagation of Free-Surface Waves Past Two Side-By-Side Fixed Squares with a Narrow Gap
Zhang, Haoyu; Liu, Shengnan; Ong, Muk Chen; Zhu, Renqing (Peer reviewed; Journal article, 2019)Two-dimensional computational fluid dynamics (CFD) simulations are carried out to investigate the gap resonance phenomenon that occurs when free-surface waves travel past twin squares in tandem. The volume of fluid method ... -
CFD simulations of violent breaking wave impacts on a vertical wall using a two-phase compressible solver
Liu, Shengnan; Gatin, Inno; Obhrai, Charlotte; Ong, Muk Chen; Jasak, Hrvoje (Peer reviewed; Journal article, 2019)Four different types of breaking wave impacts on a vertical wall are simulated using a two-dimensional two-phase Computational Fluid Dynamic (CFD) model.
