Journal ArticleDOI
The stability of the plane free surface of a liquid in vertical periodic motion
Thomas Brooke Benjamin,F. Ursell +1 more
TL;DR: In this article, the stability of the plane free surface is investigated theoretically when the vessel is a vertical cylinder with a horizontal base, and the liquid is an ideal frictionless fluid making a constant angle of contact of 90° with the walls of the vessel.
Journal ArticleDOI
An extension of the method of steepest descents
C. Chester,B. Friedman,F. Ursell +2 more
TL;DR: In this article, a new complex variable u is introduced by the implicit relation where the parameters ζ(α), A(α) are determined explicitly from the condition that the (u, z) transformation is uniformly regular near z = 0, α = 0.
Journal ArticleDOI
Edge Waves on a Sloping Beach
TL;DR: The inviscid theory predicts that at a discrete frequency the resonance is confined to the neighbourhood of the beach (inviscid edge wave), while at a cutoff frequency resonance extends a long way down the canal as discussed by the authors.
Journal ArticleDOI
The long-wave paradox in the theory of gravity waves
TL;DR: The theory of long waves in shallow water under gravity employs two different approaches, which have given rise to a well-known paradox remarked by Stokes, but hitherto not fully resolved as mentioned in this paper.
Journal ArticleDOI
The effect of a fixed vertical barrier on surface waves in deep water
F. Ursell,W. R. Dean +1 more
TL;DR: In this paper, it was shown that when the normal velocity is prescribed at each point of an infinite vertical plane extending from the surface, the motion on each side of the plane is completely determined.
