Level Set and Ghost Fluid Based Underwater Shock Analysis
Abstract
We have made significant progress towards the computation of underwater shocks. We have used state-of-the-art numerical technology, largely developed by us, including the level set method, ghost fluid method, ENO and WENO shock capturing schemes, solid fluid interaction methodology and the fast closest Point transform. We use Eulerian methods to model the detonation wave and the fluid flow and Lagrangian methods to compute the dynamic response of solid targets. Our main success so far comes in the very accurate fluid/solid interaction using our mixed scheme. We have also developed a new, higher order fast closest point transform and a module which integrates the level set method with the ghost fluid method to deal with the multiphase gas boundary. We are developing a module coupling these methods to compute reacting fluid interfaces.
