An Application of Linearized Theory to Water Entry and Water Exit Problem. Part 2 (with Ventilation)

摘要

A conformal mapping technique is used to analyze two-dimensional thin foils entering a water surface vertically with ventilations. Boundary conditions are linearized, and the gravity effect is neglected. Flow fields, pressure distributions, and drags are given in closed forms for an infinite nonsymmetrical wedge, an infinite flat plate with ventilation from the leading edge, and a finite base-vented symmetrical wedge.
