Transient Scattering from Submerged Cylindrical Shell with Appendages
Publication: Journal of Engineering Mechanics
Volume 119, Issue 7
Abstract
A numerical method is presented for determining scattered pressures from a submerged infinite cylindrical shell with radial plate appendages subjected to a transverse incident plane Heaviside pressure wave. Inside a cylindrical fluid‐control surface circumscribing the appendages, finite‐difference equations in the cylindrical domain govern the fluid‐structure interaction. The infinite region outside the control surface is transformed mathematically into a finite rectangular domain, within which finite‐difference equations with unequal spacing govern. A conditionally stable explicit scheme is used to solve the array. Numerical results indicate that the characteristic transient echo of the cylinder is obscured when the appendages are present.
