Interactions between a partially or totally immersed vibrating cantilever plate and the surrounding fluid

The dry and wet dynamic characteristics of a vertical and a horizontal cantilever square plate 1] immersed in fluid are discussed from the viewpoint of a linear hydroelasticity theory 2–5]. The surface piercing vertical plate is partially immersed in the fluid and the influence of submerged plate length on the resonance frequencies investigated. For the horizontal plate the influence of submerged depth below the free surface on the resonance frequencies is examined. Incorporated into the theoretical model is a free surface boundary condition allowing wave disturbances to be present. The interaction existing between the vibrating cantilever plate and the free surface is clearly exhibited in the calculated curves describing the generalized hydrodynamic coefficients. A limited comparison between predictions and experimental data 1] is also included.
