报告题目:Lattice Boltzmann method in industrial aero-acoustic simulations
报告摘要:35 years ago it was suggested that fluid motion can be simulated on digital computers using a simple kind of lattice gas cellular automaton (LGA) without solving the complex Navier-Stokes equations. Since then the lattice Boltzmann method (LBM), an offspring of LGA, has been advanced significantly to become a practical CFD tool in a number of industries including ground vehicle, aerospace, oil & gas and many others. Theoretically the LBM has been re-derived from the continuum classic kinetic theory, giving it a solid theoretical foundation which not only clarified certain ambiguities, but also opens the possibilities for LBM to be applied to a broad range of flow regimes including rarefied gas and complex fluid flows. In this talk I shall present the fundamental theory of LBM and discuss certain current and future developments.
报告人简介:Prof. Xiaowen Shan is currently a Chair Professor at Southern University of Science and Technology (SUSTech). He received his BS and MS degrees from Beijing University in 1985 and 1988 respectively, and his Ph. D. from Dartmouth College in 1991. From 1991 to 2012 he worked at Los Alamos National Laboratory, Microsoft, and Exa Corporation (now part of Dassault Systems SE), all in the United States. In 2012 he joined Beijing Research Center of the Commercial Aircraft Company of China (COMAC) as the Director for Aerodynamics. In 2016 he moved to SUSTech to found the Department of Mechanics and Aerospace Engineering. Dr. Shan is best known for the Shan-Chen non-ideal gas lattice Boltzmann model that he co-invented in 1993. The original paper published in Physical Review E was selected in 2018 as one of the 25 Milestones in celebrating the Journal’s 25th anniversary. In 2009 he was elected a Fellow of American Physical Society for “seminal contributions in the formulation and applications of lattice Boltzmann models for multiphase and complex fluids; and for pioneering Lattice-Boltzmann-method based fluid dynamics algorithms for real-world engineering applications.” Dr. Shan published more than 70 research papers with more than 11,000 citations accumulated.
