Ein algebraisches Verfahren zur Lösung von gemischten Anfangsrandwertproblemen aus der Theorie instationärer Gitterströmungen

摘要

AbstractMixed boundary value problems for the wave‐equation in thex‐y‐plane, with boundaries parallel to thex‐axis, are usually treated by Laplacetransformation. To use this method numerically we present it here by means of the Mikusiński‐calculus. In this paper our main interest lies in the treatment of mixed initial‐boundary value problems arising in unsteady subsonic
