This review is motivated by the fast progress in our understanding of the physics of particle-laden turbulence in the last decade, partly due to the tremendous advances of measurement and simulation capabilities. The focus is on spherical particles in homogeneous and canonical wall-bounded flows. The analysis of recent data indicates that conclusions drawn in zero gravity should not be extrapolated outside of this condition, and that the particle response time alone cannot completely define the dynamics of finite-size particles. Several breakthroughs have been reported, mostly separately, on the dynamics and turbulence modifications of small inertial particles in dilute conditions and of large weakly buoyant spheres. Measurements at higher concentrations, simulations fully resolving smaller particles, and theoretical tools accounting for both phases are needed to bridge this gap and allow for the exploration of the fluid dynamics of suspensions, from laminar rheology and granular media to particulate turbulence.

载粒子湍流:进展和前景

这篇综述的动机是我们在过去十年中对载有粒子的湍流物理学的理解取得了快速进展,部分原因是测量和模拟能力的巨大进步。重点是均匀和规范的壁边界流中的球形粒子。对最近数据的分析表明,在零重力条件下得出的结论不应在此条件之外进行推断,并且仅凭粒子响应时间并不能完全定义有限尺寸粒子的动力学。在稀薄条件下的小惯性粒子和大的弱浮力球体的动力学和湍流修改方面,已经报道了几项突破,主要是单独的。更高浓度下的测量,模拟完全解析较小的颗粒,
