"Computational modeling and experimental study of the combustion dynamics and explosive effects of energetic, multiphase systems"

固体推进剂和爆炸物属于可燃物，称为高能材料。这些能源广泛用于安全气囊充气机、火箭和爆破等应用。由于其在实际应用中的重要性，这些含能材料的可靠模型是非常可取的。对于工程规模的系统，基于非平衡多相混合物理论的Baer-Nunziato BN模型主要被考虑用于粒状含能材料，并且其推广已被应用于非均质固体颗粒流。然而，精确求解复杂BN多相方程并执行真实的模拟的可能性长期以来一直是一个非常雄心勃勃的目标。近年来，这个多相模型经历了密集的分析发展，应用数学和科学计算的新进展打开了充满希望的机会，以达到这一目标，找到准确和有效的数值解。

Solid propellants and explosives belong to the class of combustible known as energetic materials. These energy resources are extensively used for applications such as airbags inflators, rockets and demolitions. Because of its great importance for practical applications, a reliable model of these energetic materials is highly desirable. For engineering scale systems, the Baer-Nunziato BN model based on non-equilibrium multiphase mixture theory is mostly considered for granular energetic materials, and its generalization has been applied for heterogeneous solid-particle flows. However, the possibility to accurately solve the complex BN multiphase equations and perform real simulations has long represented a very ambitious goal. In recent years, this multiphase model has undergone intensive analytical development, and new advance in applied mathematics and scientific computing opens promising opportunity to reach this goal of finding accurately and efficiently its numerical solutions.
