Journal ArticleDOI
The mixing transition in Rayleigh-Taylor instability
TL;DR: In this article, a large-eddy simulation technique is described for computing Rayleigh-Taylor instability, based on high-wavenumber-preserving subgrid-scale models, combined with high-resolution numerical methods.
Journal ArticleDOI
Deflection by kinetic impact: Sensitivity to asteroid properties
TL;DR: In this paper, the authors numerically model asteroid response to kinetic impactors under a wide range of initial conditions, using an Adaptive Smoothed Particle Hydrodynamics code.
Journal ArticleDOI
Understanding the structure of the turbulent mixing layer in hydrodynamic instabilities
Peer-Timo Bremer,William H. Cabot,Andrew W. Cook,Dan Laney,Ajith Mascarenhas,Paul L. Miller,Valerio Pascucci +6 more
TL;DR: In this article, a hierarchical segmentation of the mixing envelope surface is proposed to identify bubbles and analyze analogous segmentations of fields on the original interface plane, which reveals the evolution of topological features and corroborates the observations made by scientists.
Journal ArticleDOI
Benchmarking impact hydrocodes in the strength regime: Implications for modeling deflection by a kinetic impactor
Angela Stickle,Megan Bruck Syal,Andy F. Cheng,Gareth S. Collins,Thomas M. Davison,Galen Gisler,Nicole Güldemeister,Tamra Heberling,Robert Luther,Robert Luther,Patrick Michel,Paul L. Miller,J. Michael Owen,Emma S.G. Rainey,Andrew S. Rivkin,Thomas Rosch,Kai Wünnemann,Kai Wünnemann +17 more
TL;DR: A benchmarking and validation program using different numerical codes to solve a set of standard problems to test the effects of material strength, porosity, damage models, and target geometry on the ejecta following an impact and thus the momentum transfer efficiency was designed and implemented.
Journal ArticleDOI
Modeling impact outcomes for the Double Asteroid Redirection Test (DART) mission
Angela Stickle,Emma S.G. Rainey,M. Bruck Syal,J.M. Owen,Paul L. Miller,Olivier S. Barnouin,Carolyn M. Ernst +6 more
TL;DR: In this article, the authors present results from simulations using the shock physics codes CTH and Spheral of a DART-like impact into an asteroid target, which can be used to estimate the momentum enhancement of the moon from the impact.
