Journal ArticleDOI

TL;DR: In this paper, an experimental and numerical study of the dynamics of an underwater explosion and its associated fluid-structure interaction was carried out in a specially designed test pond equipped with a high-speed camera and pressure and displacement sensors.
Journal ArticleDOI
Ghost fluid method for strong shock impacting on material interface
TL;DR: It is found that the original ghost fluid method (GFM) does not work consistently and efficiently using isentropic fix when applied to a strong shock impacting on a material interface, and a modified GFM is proposed and developed for greater robustness and consistency.
Journal ArticleDOI
A conservative interface method for compressible flows
TL;DR: A conservative interface method is presented, in which the standard finite volume scheme on Cartesian grids is modified by considering computational cells being cut by interface, which treats the topological changes naturally by combining interface description and geometric operations with a level set technique.
Journal ArticleDOI
An extended level set method for shape and topology optimization
TL;DR: The RBF multiquadric splines are used to construct the implicit level set function with a high level of accuracy and smoothness and to discretize the original initial value problem into an interpolation problem, leading to a rapid convergence to the final design insensitive to initial guesses.
Journal ArticleDOI
An immersed interface method for viscous incompressible flows involving rigid and flexible boundaries
TL;DR: An immersed interface method for the incompressible Navier-Stokes equations capable of handling both rigid and flexible boundaries is presented and is second order accurate.
