| 英文摘要 | Solid particle-gas detonation exhibits extreme complexity and is of significance for hypersonic propulsion application and dust explosion prevention, hence the current study is aim to gain insight into Aluminum (Al) particle-air detonation by means of reliable numerical approaches. Firstly, a multidimensional numerical procedure for dilute Al particle-air detonation simulation under the Eulerian-Lagrangian framework is developed, with the interphase exchanges for mass, momentum and energy being carefully treated. The simulation results for both one-dimensional (1-D) planar detonation and two-dimensional (2-D) cellular detonation are in accordance with experimental results, which demonstrates that the reliability of the present numerical procedure is validated. Next, the dynamics process, structure and characteristics of Al particle-air detonation are numerically studied for the baseline case, in which the initial particle diameter and concentration are 2 mu m and 0.3 kg/m3, respectively. Based on the 1-D simulation results, the dominant factors that influence particle motion, temperature rise, and combustion kinetics are identified. The 2-D simulation results highlight the interaction between the cellular detonation wave and the Al particle cloud, which significantly affects spatially the heterogeneous distribution of particle cloud and the particle burning rate in different pressure regions behind the detonation wave. Finally, the effects of particle diameter and particle concentration are parametrically investigated. Based on numerical results, the variation trends of detonation characteristics and structure with particle diameter and particle concentration are obtained. Scaling laws are also fitted for particle diameter versus the induction zone length of 1-D planar detonation wave and the cell size of 2-D cellular detonation wave. Furthermore, for large particle diameters and high particle concentrations, two peaks are presented in pressure profile of 1-D detonation wave, and the reason is explained using one-dimensional aerodynamic theory. |
