THE EFFECT OF SURFACE TENSION ON SHIP WAVE RESISTANCE

An extension of classical, Michell thin-ship theory to include the effect of surface tension is presented. An expression for the ship's resistance is developed and is shown to consist of two parts. The gravity-wave resistance arises from the gravity-dominated wave train which trails the ship and the ripple resistance arises from the surface-tension-dominated ripple train which precedes the ship. The first section of this study is devoted to a comparison of the new theory with that of Michell. It is shown that the character of both the gravity-wave and ripple resistance expressions are similar to Michell's integral. (Author)
