Development and Application of Three-dimensional Interior Ballistic Two-phase Flow Program Based on OpenFOAM

Abstract

To overcome the defects of long simulation period, low code reuse rate and lack ability of solving complex computation domain in the interior ballistic two-phase flow programs by the individual independent coding, a three-dimensional interior ballistic two-phase flow solver was developed in the open source finite volume software(OpenFOAM)framework. The correctness of interior ballistic solver was verified in three aspects, namely, pressure wave capture verification, global conservation verification, interior ballistic experimental results verification. The simulation analysis of ignition and flame-spreading process of the central tube dispersing system was carried out. The simulation result was compared with experiment result. The result shows that the 3D interior ballistic solver developed in this paper provides an efficient simulation tool for numerical analysis of interior ballistic problems with the ability to solve complex computational domains.
