Inertia Coefficients for Riser Configurations

Inertia coefficients for arrays of cylinders, such as might be found in risers or conductor pipes, are determined. The method used is theoretical and does not take into account viscous-related phenomena. Values of the inertia coefficient for individual cylinders in three different geometrical arrays are determined using the method of images. It is shown quite vividly the effect the geometry can have on the individual cylinder values.
