本研究关注的是一个热力学模型，可用于流体的混合物的数值模拟的发展，其中一些混合物组分不能准确地模拟由一个热完美的状态方程。详细介绍了迎风型无粘通量离散化算法，包括低速问题的预处理。结果获得了一个具有挑战性的测试情况下，涉及在高压下的液氧/气态氢混合物的燃烧，他们比较合理，以及与实验数据。
This study is concerned with the development of a thermodynamic model that can be used for numerical simulations of mixtures of fluids, whereby some of the mixture components cannot be accurately modeled by a thermally perfect equation of state. Upwind-type algorithms for the discretization of the inviscid fluxes are introduced in some detail, including preconditioning for low-speed problems. Results are obtained for a challenging test case involving the combustion of a liquid oxygen/gaseous hydrogen mixture at high pressure, and they compare reasonably well with experimental data.
