This paper presents two methods for the calculation of the virtual masses of clusters of parallel cylinders in liquid contained by an outer channel. The first method is based on classical potential flow theory, and its applicability is limited to circular cylinders in circular cylindrical channels;

β¦ Synopsis
Series of displacement functions for three-dimensional motion are assumed for a cantilevered circular cylindrical shell. The classical Rayleigh-Ritz method is used to obtain a set of equations describing the behavior of the vibrating shell. Solution of the system reduces to a standard eigenvalues problem. Computer solutions give numerical results for natural frequencies. Some mode shapes are illustrated.
A potential function is developed for a liquid contained in the shell. Its coefficients insure compatibility of the shell-liquid interface. The liquid kinetic energy is computed and added to that of the shell. Resulting natural frequencies are compared with some experimental data.
