AN APPLICATION OF LINEARIZED THEORY TO WATER ENTRY AND WATER EXIT PROBLEMS. PART I (WITH GRAVITY EFFECT),

Abstract

A method is given for obtaining the flow field under the free surface disturbed by either an impinging or an exiting thin foil of arbitrary shape; the method includes gravity effect but not the similarity rule. A time-dependent Green function is utilized for the solution. As an example, the Froude number effect of a thin two-dimensional wedge entering the water is analyzed, and the pressure distributions on the wedge, the drag, and the wave height at the wedge are given. The physical quantities at Froude Number 3 are shown to be very close to the case of infinite Froude number. (Author)
