Acoustic Diffraction by a Variable Thickness Fluid Layer.
Abstract
The effect on a particular acoustic source distribution of a variable thickness cylindrical fluid layer, denoted the diffracting layer, is investigated in this thesis. The source consists of a distribution of line sources on a rigid cylindrical baffle surrounded by a constant thickness cylindrical fluid layer. Located off center of these two cylinders is a third cylinder of a second fluid, which has a variable thickness because it is nonconcentric with the other two. The outer cylinder is surrounded by an infinite medium of the same fluid as the inner cylindrical layer. Some changes in the far field directivity pattern produced by the fluid diffracting layer will be shown in this thesis. (Author)
