Abstract
An analytical and numerical study of two-dimensional unsteady planing of a flat plate is presented. The immersion of the plate is assumed small; hence, the spray at the leading edge is represented by a square root singularity. The analogy to airfoil theory is used and the hydrodynamic problem is solved in the time domain. The time-varying wetted-length change due to the water flow is accounted for by a generalized Wagner approach. The present theory is verified by comparison with an analytical solution by Sedov (1940) for water entry of a planing plate and with the linear frequency domain solution by Bessho & Komatsu (1984) for a heaving planing plate.
