Abstract

The method of interferometric picture simulation of axial symmetrical gas flows for any initial tuning of two-beam interferometer is developed for digital interferometry. The method is based on polynomial representation of the theoretical density fields. Computer - generated interferograms are calculated for powerful explosion with central symmetry and conical supersonic flow field around sharp-tip cone when density fields depend on one parameter only. Results can be used in analisys of interferometric picture in the real experimental conditions. In addition, the comparison of experimental with computer - generated pictures is used to affirm adequacy of the theoretical model for description of visualized phenomena.
