The Disturbance Produced by an Oscillatory Pressure Distribution in Uniform Translation on the Surface of a Liquid.

摘要

The current development of air cushion supported marine vehicles has kindled a renewed interest in the analysis of water waves produced by surface pressure distributions. Recently, unsteady problems have been investigated in order to obtain insight into various aspects of the dynamic performance of air cushion supported vehicles. The problem treated in this paper is closely related to the translating submerged source of pulsating strength. Presented is an entirely analytical result for the two-dimensional surface elevation that is valid for the entire field. Results are given for both a delta function and a uniform pressure distribution.
