Problem of Studying the Acoustic and Hydrodynamic Properties of the Medium that Occupies a Domain Shaped As a Three-Dimensional Rectangular Wedge

Abstract

A boundary-value problem for a three-dimensional Helmholtz equation in a domain shaped as an unbounded rectangular wedge is under consideration. An exact solution to this boundary-value problem is constructed in the form of a packed block element necessary for investigating more complex and even mixed problems for block structures. Packed blocks are joined into a block structure by creating quotient topologies of the topological spaces of blocks, and the equivalence relations are interblock boundary conditions.
