Abstract:

The Civil Engineering Laboratory is conducting a research program with the goal of developing mathematical models to aid in the computer simulation of the behavior of cable structures in the ocean. One of the major goals of the program has been prediction of the normal drag of a vibrating cable. Two simulation models have been independently developed which, when used together, result in the capability of predicting the normal drag of a vibrating cable. The models predict the frequency and amplitude of the cable vibrations based upon the mechanical properties of the cable and the fluid flow properties a factor is then computed which, when multiplied by the non-vibrating drag coefficient for the cable, results in the effective drag coefficient for the cable. Thus, the non-vibrating drag coefficient must be known. A survey has been conducted to identify available drag coefficient of non-vibrating cables and to assess the quality of the data as to its applicability for use in design of undersea cable structures.
