Wave Induced Flow around Submerged Sloping Plates

Wave attenuation and flow kinematics of an inclined thin plate acting as an alternative coastal protection structure

“…This net flow is seen to be accompanied by an upward directed vertical component on the seabed. This upward directed vertical component of the sub-plate flow was also seen in Murakami et al's [13] results (see Fig. 11-1 in [13]), and it is likely to be a consequence of the higher water level at the landward side compared to seaward side.…”

“…Parsons and Martin [14] developed a numerical model to study the reflection from fully submerged vertical, horizontal, and inclined plates, which was later extended for obliquely incident waves by Midya et al [12]. Murakami et al [13], in their experimental study, argued that a seaward steady streaming flow occurs beneath an inclined submerged plate and they measured the reflection, transmission, and energy dissipation coefficients. Rao et al [17] are another group of researchers who conducted experiments to investigate the wave reflection and transmission from a submerged inclined plate.…”

Performance of an inclined thin plate in wave attenuation

“…Parsons and Martin (1992) developed a numerical model to study the reflection from fully submerged vertical, horizontal and inclined plates (Later, their study was extended for obliquely incident waves by Midya et al 2001). Murakami et al (1994) showed that a persistent flow occurs beneath an inclined submerged plate and measured the reflection, transmission and energy dissipation coefficients in their experimental study. Recently, Rao et al (2009) conducted experiments to see the wave reflection and transmission from a submerged inclined plate.…”

Numerical Investigation on Higher-Order Harmonic Waves Induced by a Submerged Inclined Plate

“…In [24], the problem of two submerged inclined plates placed side-by-side was considered, and better performance in terms of wave reflection was found when compared to the case of a single inclined plate. The effect of the inclination direction (i.e., inclined upstream or downstream) was investigated by using the physical experiments in combination with numerical simulations in [25]. In [26], the authors found that a thin plate with an inclination angle of 60 • works well across all the wave parameters considered, and a maximum reduction of 40% in the wave height was found.…”
