The first decade of unified gas kinetic scheme
arXiv:2102.01261
Abstract
In 2010, the unified gas kinetic scheme (UGKS) was proposed by Xu et al . (A unified gas-kinetic scheme for continuum and rarefied flows, Journal of Computational Physics, 2010). In the past decade, many numerical techniques have been developed to improve the capability of the UGKS in the aspects of efficiency increment, memory reduction, and physical modeling. The methodology of the direct modeling of the UGKS on discretization scale provides a general framework for construction of multiscale method for multiscale transport processes. This paper reviews the development and extension of the UGKS in its first decade.
