An Adaptive Fourier Spectral Method for the Vlasov-Poisson system
Seung Yeon Cho, Giovanni Russo
The paper introduces an adaptive Fourier spectral method with high-order time splitting to dynamically expand the wavenumber domain and avoid artificial filtering when simulating t…
Convergence of an Eulerian scheme for the Vlasov-Poisson-BGK model
Seung Yeon Cho, Sungsu Park, Seok-Bae Yun
The Vlasov-Poisson-BGK (VPBGK) model is a kinetic model for describing the dynamics of collisional plasmas. Although various numerical schemes have been developed for it, a corresp…
Asymptotic Analysis of IMEX-RK Methods for ES-BGK Model at Navier-Stokes level
Sebastiano Boscarino, Seung Yeon Cho
Implicit-explicit Runge-Kutta (IMEX-RK) time discretization methods are very popular when solving stiff kinetic equations. In [21], an asymptotic analysis shows that a specific cla…
A conservative semi-Lagrangian scheme for the ellipsoidal BGK model of the Boltzmann equation
Sebastiano Boscarino, Seung Yeon Cho, Giovanni Russo +1
In this paper, we propose a high order conservative semi-Lagrangian scheme (SL) for the ellipsoidal BGK model of the Boltzmann transport equation. To avoid the time step restrictio…
