A local velocity grid conservative semi-Lagrangian schemes for BGK model
Sebastiano Boscarino, Seung Yeon Cho, Giovanni Russo
Most numerical schemes proposed for solving BGK models for rarefied gas dynamics are based on the discrete velocity approximation. Since such approach uses fixed velocity grids, on…

High Order Semi-implicit WENO Schemes for All Mach Full Euler System of Gas Dynamics
Sebastiano Boscarino, Jing-Mei Qiu, Giovanni Russo +1
In this paper, we propose a new high order semi-implicit scheme for the all Mach full Euler equations of gas dynamics. Material waves are treated explicitly, while acoustic waves a…
