Data-driven Modeling of Two-Dimensional Detonation Wave Fronts
[article]
2021
arXiv
pre-print
Preserved Fulltext
Historical experimental testing of high-altitude nuclear explosions (HANEs) are known to cause severe and detrimental effects to radio frequency signals and communications infrastructure. ...
In order to study and predict the impact of HANEs, tractable computational approaches are required to model the complex physical processes involved in the detonation wave physics. ...
High-Altitude Nuclear Explosions HANEs are nuclear explosions that detonate within Earth's atmosphere above an altitude of approximately 30 kilometers. ...

We present two-dimensional hydrodynamics simulations of near-Chandrasekhar mass white dwarf (WD) models for Type Ia supernovae (SNe Ia) using the turbulent deflagration model with deflagration-detonation ...
We find that dependencies of the nucleosynthesis yields on the metallicity and the central density (WD mass) are large. ...
Once this condition is satisfied, we put in the initial C-detonation in the form of 2D bubble (a ring) at that point, and allow that detonation to freely evolve. ...
