Numerical investigation on nonlinear evolution behavior and water particle velocity of wave crests for narrow-band wave field with Gaussian spectrum
2023, Ocean EngineeringCitation Excerpt :Apart from the wave field characteristics, the analysis of water particle velocity of Freak wave crests has the increasing concern due to the demand of wave load calculation for marine structures under extreme waves (Chang et al., 2021; Qin et al., 2017; Zhao et al., 2014). It started from the early experimental work of Sand et al. (1990) along with the following detailed Freak wave kinematics measurement by experiments (Grue et al., 2003; Grue and Jensen, 2006; Grue et al., 2014). Besides, the numerical investigations and related algorithms for obtaining the velocity field under wave crest were addressed (Sergeeva and Slunyaev, 2013; Cui et al., 2013; Alberello and Iafrati, 2019; Tao et al., 2021).

2012, Journal of Fluids and StructuresCitation Excerpt :Chang and Liu (1999) performed experimental measurements to investigate the turbulence nature of the post-breaking events generated by breaking waves in water of intermediate depth. More recent studies using particle image velocimetry (PIV) technology provide more detailed velocity, turbulence, and void fraction data and analysis (Blenkinsopp and Chaplin, 2007; Drazen and Melville, 2009; Grue and Jensen, 2006; Kimmoun and Branger, 2007). Early CFD studies are for 2-D cases and focused on the wave breaking process and velocity (Chen et al., 1999; Watanabe and Saeki, 2002) field.
Impulsive plunging wave breaking downstream of a bump in a shallow water flume-Part II: Numerical simulations
2012, Journal of Fluids and StructuresCitation Excerpt :Early experimental studies are focused on wave geometric properties (Bonmarin, 1989), wave breaking process (Tallent et al., 1990), energy dissipation (Melville, 1994), jet characteristics and air entrainment (Chanson and Fang, 1997), and turbulence (Chang and Liu, 1999). With the Particle Image Velocimetry (PIV) techniques, more detailed velocity field, turbulence, and void fraction data and analysis have been investigated in recent studies (Blenkinsopp and Chaplin, 2007; Deane and Stokes, 2002; Drazen and Melville, 2009; Grue and Jensen, 2006; Kimmoun and Branger, 2007; Melville et al., 2002). Due to the technical difficulties, the experimental measurements can only be done in the water region, and detailed description of the flow field in the energetic wave breaking region is not available.
