recoilless gun flow characteristics overpressure contours safety zones
TJ012. 2
In order to study complex characteristics of the flow field of a recoilless gun,the front and back flow field of the recoilless gun with moving projectile is numerically simulated using the finite volume method,AUSM+scheme and chimera grids technique. According to the simulation results,sequential computational shadowgraphs and overpressure contours around the gun are plotted. The formation and development processes of the whole flow fields are discussed in detail. In terms of the relevant military standards,the safety zones for the gun crew are also analyzed. These results are very significant for understanding the characteristics of the flow field of the recoilless gun and predicting the blast damage on the gun crew.
