Passive scalar equation in a turbulent incompressible Gaussian velocity field
S. V. Lototskii, B. L. Rozovskii University of Southern California
Abstract:
The time evolution of a passive scalar in a turbulent homogeneous
incompressible Gaussian flow is considered. The turbulent nature of the
flow results in non-smooth coefficients of the corresponding evolution
equation. A strong solution (in the probabilistic sense) of the equation is
constructed by using the Wiener Chaos expansion, and properties of the
solution are studied. In particular, a certain $L_p$-regularity of the solution and a representation formula of Feynman–Kac type (or a Lagrangian formula) are among the
results obtained. The results can be applied to both viscous and conservative flows.
