Abstract A new quasi-direct numerical simulation (q-DNS) solver named combustionFoam, capable of simulating reacting flows at arbitrary Mach number with a detailed chemical reaction mechanism, has been developed. This solver is implemented based on reactingFoam-solver from OpenFOAM-v7. The main improvements are a mixture-averaged formula transport model and ability to simulate reacting flows at arbitrary Mach number. The transport model is implemented by developing an data exchange interface to couple OpenFOAM® with Cantera. To damped nonphysical oscillations near shocks, a hybrid KT/KNP approach derived by Kraposhin et al. [18] is adopted. This solver was validated by two test cases: (1) a low speed steady two dimensional non-premixed counterflow diffusion flame; (2) a supersonic transient one dimensional detonation waves. Comparisons of the results with data from other solvers and literatures are carried out and good agreements are obtained.

可压缩反应流的准直接数值模拟求解器

摘要 开发了一种新的准直接数值模拟（q-DNS）求解器，名为burningFoam，能够模拟任意马赫数下的反应流，并具有详细的化学反应机理。该求解器基于 OpenFOAM-v7 的 reactingFoam-solver 实现。主要改进是混合平均公式传输模型和模拟任意马赫数反应流的能力。传输模型是通过开发数据交换接口来实现的，以将 OpenFOAM® 与 Cantera 结合起来。为了抑制冲击附近的非物理振荡，Kraposhin 等人提出的混合 KT/KNP 方法。[18] 采用。该求解器通过两个测试案例进行验证：（1）低速稳定二维非预混逆流扩散火焰；(2) 超音速瞬态一维爆震波。
