Nonlinear magnetohydrodynamic modeling of ideal ballooning modes in high- Wendelstein 7-X plasmas
Yao Zhou, K. Aleynikova, Chang Liu +1
We present nonlinear magnetohydrodynamic (MHD) simulations of high- Wendelstein 7-X plasmas using the stellarator extension of the M3D- code, building on the recent work th…
Available Energy and Ground States of Convective Hydrodynamic and Hydromagnetic Instabilities
Kaixuan Fan, Yao Zhou
We propose a method for predicting the nonlinear saturation level of convective instabilities in neutral and magnetized fluids. The method combines Gardner's restacking algorithm,…
Direct Numerical Simulations of Oxygen-Flame-Driven Deflagration-to-Detonation Transition in Type Ia Supernovae
Xiaoyu Zhang, Lile Wang, Yang Gao +1
We present direct numerical simulations demonstrating deflagration-to-detonation transition (DDT) driven by oxygen flames in Type Ia supernova progenitors. Using the Castro hydrody…
Deep Neural Networks for Modeling Astrophysical Nuclear Reacting Flows
Xiaoyu Zhang, Yuxiao Yi, Lile Wang +3
In astrophysical simulations, nuclear reacting flows pose computational challenges due to the stiffness of reaction networks. We introduce neural network-based surrogate models usi…
