| description | A numerical parametric study was conducted to better understand the Hydrodynamic Ram (HRAM) event. The model considered a projectile penetrating a box which contains water either partially or fully. A standard model was developed and validated against the available experimental data. Then, each parameter was varied individually to determine its effect during the HRAM event. The parameters considered were the water filling level in the box, its wall thickness, projectile impact velocity, projectile mass, impact angle, and projectile shape. The effect of each individual parameter was studied, and the effects of different parameters were compared. Then, an attempt was made to predict the combined effects of multi-variables. Even though the results and discussion are for the specific geometric and material data used in this study, the present findings are expected to provide valuable insights to the qualitative characteristics of the HRAM event. |
