Extreme properties of oscillations of an elliptical float

Cover Page

Abstract


Extreme in amplitude and frequency properties of oscillations of a thin elongated flat body of elliptical form in the vicinity of the interface of stably stratified ideal fluids are studied. Numerical and analytical procedures have been developed for solving a self-consistent boundary value problem on an asymptotically large time range. The time-dependences of the amplitude decay and frequency of oscillations are obtained. The comparison with similar characteristics, found early by the authors for floats of other forms, is carried out, and significant quantitative and qualitative differences were established.
