Hydrodynamics of an asymmetric heave plate for a point absorber wave energy converter

Hydrodynamic damping of solid and perforated heave plates oscillating at low KC number based on experimental data: A review

“…Also, with the help of flow visualization, Thiagarajan and Troesch (1994) asserted that at large KC numbers, the flow pattern around the edges of the plate is completely anti-symmetric. Other studies have also been carried out on this subject by Sireta et al (2008), Rusch et al, 2020 andMentzoni et al (2020). By defining a critical KC number and with the help of the drag variation curve, Tao and Thiagarajan (2003-b) categorized the flow regime amplitude of horizontal oscillating plates into three regimes at low KC numbers (Fig.…”

Efficient Nonlinear Hydrodynamic Models for Wave Energy Converter Design—A Scoping Study

“…A number of studies seek to identify appropriate drag coefficients using data from PWT experiments on scale model WECs [204][205][206][207][208][209]. The work in [207,208] consider the drag on a heave plate for an HPA and show that identified coefficients have strong intracycle variations, but that constant coefficients can nonetheless result in reasonable model agreement with the data.…”

The work in [207,208] consider the drag on a heave plate for an HPA and show that identified coefficients have strong intracycle variations, but that constant coefficients can nonetheless result in reasonable model agreement with the data. Indeed, while identifying the drag from PWT data generally allows the coefficients to be tuned so that the numerical and experimental results agree well, it is not guaranteed that the viscous effects will scale proportionally from the PWT to the full-scale WEC (as discussed in Section 2.2.4).…”
