Fluid-Structure Interaction Simulation of Detonation-Driven Rupture Events of Thin-Walled Tubes with a Parallel Adaptive Level Set Method

چکیده
Technically relevant fluid-structure interaction simulation of detonation-induced dynamic response of thin-walled solid structures requires an efficient detonation solver that can cope with large deformations as well as arbitrary topology changes of the computational domain. We present a parallel adaptive method that uses a scalar level set function to represent embedded evolving solid boundaries on an Eulerian Cartesian mesh and that employs a constant volume burn model for efficient detonation propagation in a shockcapturing finite volume scheme. As realistic computational application, we consider the induction of large plastic deformations and the fracture of thin aluminum tubes due to the passage of fully developed detonations in ethylene-oxygen mixtures.
