V.B.Galanenko, D.V.Galanenko On accounting the solution singularity in calculation of the normal waves diffraction in a plane waveguide |
Acoustic bulletin, Vol. 4 ¹ 2, (2001) |
| A method of accounting the singularity in the solution derivatives for a problem of the normal wave diffraction on the angle border points in the flat waveguide with liquid filling is offered. It lies in the solution subdivision in two terms, one of which contains the singularity, satisfyng herewith the boundary conditions on the waveguide surfaces, and the other is a regular one. The offered computation method allows to obtain an approximate solution, that contains the singularity explicitly. The estimation of the method efficiency using the criteria of the power streams balance and the partial solutions matching deficiency in the subdomains is given. |
