Скачать или смотреть blastFoam | Air-water shock bubble interaction

A blastFoam simulation of the interaction between a strong shock in water and an air bubble. The shock wave has a Mach number of 1.422, and is traveling in water. The post-shock region is initially at rest and includes an air bubble with a radius of 0.2 m. Results are compared to the original results of Shyue 1999 and Zheng 2008.

The calculation takes approx. 10 minute to run on a four core desktop at the reference resolution (e.g. 24x20 cells with a maximum refinement level of 4). Reference solution and plots from this run are in the "referencePlots" directory. The user run results must be viewed using a graphical viewer.

blastFoam is a free and open-source solver for multi-component compressible flow, based on the five-equation model, with application to high-explosive detonation, explosive safety and airblast. The solver has been validated through the use of experimental data from laboratory, scaled, and full-scale tests. Recent work has focused on validation for engineering-scale problems, and near-contact settings.
