论文摘要
与Lee-Tarver反应模型一起，引入了基于颗粒按需方法的动力学模型，用于气相爆发流体动力学。提出的模型在二维晶格上实现，并通过一组基准进行验证。使用Chapman-Jouguet理论进行定量验证，直至在一个维度上的爆炸波速度。测试了模型的各向同性以及渐近爆炸波速度的二维向外扩展爆炸。 MACH反射角在设置中得到了验证，这些设置包括相互作用的强烈弓形冲击，引起了爆炸。计算球形爆炸以显示三维模拟的建议模型的生存能力。
A kinetic model based on the Particles on Demand method is introduced for gas phase detonation hydrodynamics in conjunction with the Lee--Tarver reaction model. The proposed model is realized on two- and three-dimensional lattices and is validated with a set of benchmarks. Quantitative validation is performed with the Chapman--Jouguet theory up to a detonation wave speed of Mach 20 in one dimension. Two-dimensional outward expanding circular detonation is tested for isotropy of the model as well as for the asymptotic detonation wave speed. Mach reflection angles are verified in setups consisting of interacting strong bow shocks emanating from detonation. Spherical detonation is computed to show viability of the proposed model for three dimensional simulations.
