惯性粒子的密度:精确可解的2D模型

Density of Inertial Particles: Exactly Solvable 2D Models

Leonid Piterbarg

摘要:

惯性粒子在二维驱动的高斯白噪声强迫。对于两个例子的强迫(可压缩和不可压缩)的上限和下限被发现的焦散线的平均数作为斯托克斯数的函数。通过数值计算验证了该边界的有效性。

英文摘要:

Inertial particles in 2D driven by a Gaussian white noise forcing are considered. For two examples of the forcing (compressible and incompressible) upper and lower bounds are found for the mean number of caustics as a function of Stokes number. Efficiency of the bounds is verified by numerical methods.
