随机速度场中惯性粒子的聚团与碰撞
Clustering and collision of inertial particles in random velocity fields
摘要：
模拟了小尺度湍流，分析了在光滑随机速度场中，成团效应对惯性粒子碰撞率的影响。对于粒子速度的弛豫时间和场的特征时间之间的比值较小的值，团簇的作用是使更高能量的碰撞不太可能发生。结果是独立的流动维数，是由于只有在苛性形成的过程中的碰撞的起源。
英文摘要：
The influence of clustering on the collision rate of inertial particles in a smooth random velocity field, mimicking the smaller scales of a turbulent flow, is analyzed. For small values of the the ratio between the relaxation time of the particle velocity and the characteristic time of the field, the effect of clusters is to make more energetic collisions less likely. The result is independent of the flow dimensionality and is due only to the origin of collisions in the process of caustic formation.
