中文摘要
小行星9311545 研究多个涡流之间的相互作用。这些相互作用与湍流动力学有关。该方法主要是数值和部分理论的基础上,从动力系统理论,物理动力学和重整化群理论的工具。数值建模将来自直接数值模拟。 结果将有相关的湍流的各个方面,特别是嵌入涡结构的破碎和合并或重新连接。这些机制的澄清将影响更合理的模型的发展,用于预测湍流在工程的各个领域。 ***
英文摘要
9311545 Aref Research is to be conducted on the interaction between multiple vortices. These interactions are relevant to the dynamics of turbulence. The approach is primarily numerical and partly theoretical, based on tools from dynamical systems theory, physical kinetics, and renormalization group theory. Numerical modeling will be from Direct Numerical Simulations. Results will have relevance to various aspects of turbulent flow, particularly the fragmentation and merging or reconnection of embedded vortex structures. Clarification of such mechanisms will impact the development of more rational models for predicting turbulent flows in various areas of engineering. ***
