Abstract

Author(s): Yong Wang (王勇), Chengwen Zhong (钟诚文), and Sha Liu (刘沙) In this paper, the original discrete unified gas kinetic scheme (DUGKS) is extended to the arbitrary Lagrangian–Eulerian (ALE) framework to enable simulation of low-speed continuum and rarefied flows with moving boundaries. For the proposed ALE-type DUGKS, the mesh motion velocity is introduced in t... [Phys. Rev. E 100, 063310] Published Tue Dec 31, 2019
