Learning the Optimal Hydrodynamic Closure
Florian Kogelbauer, Candi Zheng, Ilya Karlin
We present the optimal hydrodynamic model for rarefied gas flows relative to a given kinetic model by combining the recent theory of slow spectral closure with machine learning tec…
Phase Transition in Extended Thermodynamics Triggers Sub-shocks
Candi Zheng, Yang Wang, Shiyi Chen
Extended thermodynamics commonly uses polynomial moments to model non-equilibrium transportation, but faces a crisis due to sub-shocks, which are anomalous discontinuities in gas p…
Stabilizing the Maximal Entropy Moment Method for Rarefied Gas Dynamics at Single-Precision
Candi Zheng, Wang Yang, Shiyi Chen
The maximal entropy moment method (MEM) is systematic solution of the challenging problem: generating extended hydrodynamic equations valid for both dense and rarefied gases. Howev…
Data-Driven Constitutive Relation Reveals Scaling Law for Hydrodynamic Transport Coefficients
Candi Zheng, Yang Wang, Shiyi Chen
Finding extended hydrodynamics equations valid from the dense gas region to the rarefied gas region remains a great challenge. The key to success is to obtain accurate constitutive…
