Abstract Scope |
This study aims to mitigate the high-pressure spikes generated in underwater implosions. Experiments were performed underwater in a pressure vessel, where thin-walled aluminum 6061 cylindrical shells were placed, and the hydrostatic pressure was increased until the tubes collapsed. To mitigate the pressure pulses radiated into the fluid by the implosion of the tubes, closed cell PVC foam rods of varying densities were placed concentrically inside of the aluminum tubes. Digital Image Correlation was employed to obtain the full-field displacements of the aluminum tubes during implosion. The pressure fields created during the structural collapse were recorded with tourmaline pressure sensors. The foam rods were able to decrease the peak pressure generated by a substantial amount. Fully coupled Fluid-Structure Interaction Finite Element models were created using the Abaqus software to obtain the structural deformation energy in the aluminum tubes after implosion, as well as the energy absorbed by the foam rods. |
