Experiments on the water entry of curved wedges: High speed imaging and particle image velocimetry

Assessment of PIV-based analysis of water entry problems through synthetic numerical datasets

“…Only few efforts have documented a direct measurement of the hydrodynamic loading at selected locations on the impacting structure through pressure gauges (Charca et al, 2009;Battley and Allen, 2011;Stenius et al, 2013). Recently, a non-invasive contactless experimental methodology based on particle image velocimetry (PIV) (Raffel et al, 1998;Van Oudheusden, 2013) has been proposed to experimentally reconstruct the pressure field in water entry problems (Panciroli and Porfiri, 2013;Nila et al, 2013;Panciroli et al, 2015;Shams et al, 2015;Jalalisendi et al, 2015). This methodology enables the estimation of the slamming load on the whole structure that is wetted by the water and of the energy imparted to the pile-up and the spray jets during impact.…”

“…The PIV-based methodology reconstructs the pressure field through the integration of Navier-Stokes (Panciroli and Porfiri, 2013;Panciroli et al, 2015;Jalalisendi et al, 2015) or Poisson (Nila et al, 2013;Shams et al, 2015) equations using the velocity data from PIV measurements. Results presented in Panciroli and Porfiri (2013), Panciroli et al (2015), Nila et al (2013), Shams et al (2015), and Jalalisendi et al (2015) demonstrate the possibility of estimating the distributed hydrodynamic loading on wedges of different deadrise angles and curvatures as well as dissecting the energy imparted to the pile-up and the spray jets.…”

Higher-order theories for the free vibrations of doubly-curved laminated panels with curvilinear reinforcing fibers by means of a local version of the GDQ method

“…Due to their outstanding performance and efficiency shell structures have acquired an important role in many engineering fields, as stated in the review by Liew et al [48] and in the researches carried out by Qatu [49,50]. For example, the importance of these kinds of structures is highlighted in some recent papers about civil, naval [51][52][53][54][55] and aerodynamics [56][57][58][59][60][61][62][63] applications. Furthermore, these characteristics have been emphasized mostly by the use of composite materials, such as laminated composites, in order to obtain the best engineering properties with respect to conventional materials.…”

Harmonic oscillations of a thin lamina in a quiescent viscous fluid: A numerical investigation within the framework of the lattice Boltzmann method

“…Several practical applications have already been successfully investigated such as the design of micro-air vehicles [1][2][3][4][5][6], the development of underwater energy harvesting systems [7][8][9] and the prediction of the hydrodynamic loads acting upon the hull of a ship [10][11][12][13]. From a fundamental viewpoint, the computation of the hydrodynamic load acting upon a vibrating beam (in a quiescent viscous fluid) is a contemporary topic of special interest [14][15][16][17][18].…”
