Detailed Simulations of Shock-Bifurcation and Ignition of an Argon-diluted Hydrogen/Oxygen Mixture in a Shock Tube
Detailed simulations of the bifurcation and ignition of an Argon-diluted Hydrogen/Oxygen mixture in the two-stage weak ignition regime are performed. An adaptive meshrefinement (AMR) technique is employed to resolve all relevant physical scales that are associated with the viscous boundary-layer, the reaction front, and the shock-wave. A high-order hybrid WENO/central-differencing method is use...
متن کاملScalability of Hydrodynamic Simulations
Many hydrodynamic processes can be studied in a way that is scalable over a vastly relevant physical parameter space. We systematically examine this scalability, which has so far only briefly discussed in astrophysical literature. We show how the scalability is limited by various constraints imposed by physical processes and initial conditions. Using supernova remnants in different environments...
متن کاملModeling of multi-interface, diverging, hydrodynamic experiments for the National Ignition Facility
The National Ignition Facility (NIF) will soon provide experiments with far more than ten times the energy than has been previously available on laser facilities. In the context of supernova-relevant hydrodynamics, this will enable experiments in which hydrodynamic instabilities develop from multiple, coupled interfaces in a diverging explosion. This paper discusses the design of such blast-wav...
متن کامل3D Lagrangian Hydrodynamic Simulations
MULTI is a computer program that simulates the behavior of matter at the high densities of energy typically found in both, Inertial Fusion Energy (IFE), and related experiments of beam-matter interactions. The primitive one-dimensional version was published in [1], and the most recent two-dimensional extension has been described in [2]. The code is freely available from http://server.faia.upm.e...
متن کاملSpherical Strong-Shock generation for Shock-ignition inertial fuSion
LLE Review, Volume 141 48 Introduction Shock ignition (SI)1–5 is an advanced concept in inertial confinement fusion (ICF)6 that is very promising and has the potential to provide significantly higher gains than conventional hot-spot ignition.7 SI is a two-step process where the fuel compression and ignition phases are separated by applying a highly shaped laser pulse with a duration of several ...
