Stability and large-time behavior for the N-Dimensional Euler-FENE dumbbell model near an equilibrium
Zheng-an Yao, Ruijia Yu
This paper studies the N-dimensional FENE dumbbell model without velocity dissipation, focusing on the stability and decay of perturbations near the steady solution $(0,\pin)$. Due…

Partitioned Conservative, Variable Step, Second-Order Method for Magneto-hydrodynamics In Elsässer Variables
Zhen Yao, Catalin Trenchea, Wenlong Pei
Magnetohydrodynamics (MHD) describes the interaction between electrically conducting fluids and electromagnetic fields. We propose and analyze a symplectic, second-order algorithm…

Incompressible limit for the 3D compressible FENE dumbbell model
Jincheng Gao, Jiahong Wu, Zheng-an Yao +1
In this work, we study the global-in-time incompressible limit of the compressible FENE dumbbell model on the three-dimensional torus T^3, where the incompressible limit is driven…
