| 中文摘要 | 近年来,随着计算技术的发展,大涡模拟和直接模拟已经成为研究两相相间作用机制的重要手段之一。基于颗粒相质点轨道模型的多向耦合数值模拟是目前探索颗粒弥散机制和湍流调制机理的主要研究方式。颗粒全分辨直接模拟能够给出颗粒相足够多的信息,更加细观的反映颗粒的存在(如引起的尾涡等)对湍流的调制机理。该文针对气固两相流动中的三类基本原形流,重点综述了大涡模拟以及直接模拟研究两相湍流规律和机理的进展与成果。; Recently, with the development of high performance computation technology, large eddy simulation and direct numerical simulation have already become one of the most important approaches in study of two-phase inter-phase interaction mechanisms.Numerical simulation based on mass point particle trajectory model and multi-way coupling model is mainly used to explore the particle dispersion by turbulence and turbulence modulation by particles.Particle fully-resolved direct numerical simulation provides more information of particle phase-vortex structures in particle wakes, which contains complete mechanisms due to the existence of finite-size particles.Focused on three basic flow prototypes, recent investigations on particle-laden turbulence mechanisms by means of large eddy simulation, direct numerical simulation and particle fully-resolved direct numerical simulation are reviewed in this paper.; 国家自然科学基金项目(50706021); 教育部高校博士点基金项目(20070003018) |
