A Conservative Version of the Method of Characteristics with a Floating Grid in Problems of Gas Dynamics

Abstract

Test calculations of the motion and reflection of individual waves in a long tube have been performed applying newly developed and known schemes with a floating grid. Waves in the corresponding experiment were formed using a specially designed single-cycle generator. The version presented is shown to have a significant advantage in calculation time over the discontinuity decay method, in which the computational grid density must be increased significantly to obtain the desired correspondence with the real wave pattern.
