Wave Making by an Underwater Explosion.

摘要

This paper is a historical account of wave making experiments made during and immediately after World War II, from the smallest to the largest scale including the Atom Baker Bikini. The various theories of explosive wave making are discussed and comparisons are made between the observations and the theoretical expectations. Scaling laws are examined for the two distinct cases: explosion bubble containment (deep case) and explosion bubble blowout (shallow case). The influence of the sea bottom is considered. A general conclusion is reached that it is possible to reconcile theory and experiment within a factor of two with regard to wave amplitude and within a few percent with regard to wave period. The number of experiments which are directly applicable to the conditions imposed by theory is limited. Theory in some cases assumes the presence of a rigid bottom, and in other cases no bottom at all; whereas in most experiments a non rigid bottom is present. A synthesis of all these results is made leading to a semiempirical prescription by which explosively generated waves may be predicted. The conclusions are not inconsistent with later work in this field done in the last decade. (Author)
