Fluid-loading influence coefficients for a finite cylindrical shell

Abstract

The fluid radiation loading exhibited by a finite cylindrical shell with rigid immovable end plates is investigated by implementing the methods of Fourier integral transforms. The solution is obtained for a generalized velocity distribution on the cylindrical surface. The numerical solution for a radially pulsating surface is utilized as the basis for comparison to previous investigations. In addition, the radiation loading displayed by the low-order modes of a simply supported shell section is obtained, and the relative effect of the imposed condition of an infinite cylindrical baffle embodying the shell is ascertained. It is shown that the classical solution for a vibrating band on an otherwise rigid surface offers a reasonable approximation in the determination of the fluid radiation loading imparted to a finite cylindrical shell with rigid end closures.
