S. V. Lototsky, B. L. Rozovskii

摘要:

本文考虑湍流均匀不可压高斯速度场中的被动标量方程。场的湍流性质导致方程中的非光滑系数。利用Wiener混沌构造了该方程在随机意义下的强解,并研究了解的性质。结果适用于粘性和保守运动。

英文摘要:

Passive scalar equation is considered in a turbulent homogeneous incompressible Gaussian velocity field. The turbulent nature of the field results in non-smooth coefficients in the equation. A strong, in the stochastic sense, solution of the equation is constructed using the Wiener Chaos, and the properties of the solution are studied. The results apply to both viscous and conservative motions.
