The project concerns the design of discrete velocity models for the numerical simulation of gas flows in the transition region between rarefied gas theory and fluid dynamics.Based on the results of a previous project, the focus lies on the simulation of real gas effects, in particular gas mixtures. Another focus is the investigation of algebraic properties, particularly of three-dimensional models.We will derive and implement efficient numerical schemes on parallelized architectures (CUDA).

该项目涉及为稀薄气体理论和流体动力学之间的过渡区域的气体流动的数值模拟设计离散速度模型。在以前项目的结果的基础上，重点在于模拟真实的气体效应，特别是气体混合物。另一个重点是代数性质的研究，特别是三维模型。我们将推导和实现高效的数值方案上并行架构（CUDA）。
