Gas-Solid Flow Model for Medium Caliber Naval Gun
Authors: , ,
Abstract: In this work the computational fluid dynamics for two-phase flow of the interior ballistic process is modeled. This model is solved numerically in order to predict the interior ballistic performance. The numerical simulation is carried out by MacCormack’s technique depending on the governing equations of the two-phase flow. A self-adapting method is used to expand the computational domain of the projectile motion. The moving control volume conservation method is used to adapt the moving boundary. This approach is applied to 76mm medium caliber naval gun with guided projectile. The simulation of the two-phase flow model with the projectile motion gives a good agreement between simulation results and experimental results.
