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

固体推进剂和炸药属于可燃物，即高能材料。这些能源被广泛用于安全气囊充气机、火箭和爆破装置等应用。由于其在实际应用中的重要性，一个可靠的含能材料模型是非常需要的。对于工程尺度系统，基于非平衡多相混合理论的Baer-Nunziato BN模型主要考虑颗粒状含能材料，其推广应用于非均质固-颗粒流动。然而，精确求解复杂BN多相方程并进行真实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，这种多相模型经过了深入的分析发展，应用数学和科学计算的新进展为实现准确有效地找到其数值解的目标提供了良好的机会。

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.
