MATHEMATICAL GENERATION OF A REALISTIC SEA,
Abstract
Expressions are derived from which the instantaneous values of the surface elevation and orbital (particle) velocity encountered by a hydrofoil craft or other object traversing a realistic sea can be calculated as a function of time. These expressions, which are given in terms of an arbitrary energy spectrum were programmed for calculation on an electronic digital computer (using the Neumann Spectrum) for purposes of checking the reliability of the derived expressions and the computation scheme. The values of various significant parameters, such as the mean and 1/nth highest maxima of the surface elevation are found to be in good agreement with predicted (from statistical theory) and measured values. The concept of the relative broadness of various spectra is also discussed and incorporated into the checking scheme. (Author)
