Introduction to One-Dimensional Turbulence Models
Abstract: One-Dimensional Turbulence (ODT) is a stochastic model which mimics the dynamics of turbulent flows on a one-dimensional domain. Turbulent stirring is represented by stochastic mapping events, with physically realistic length and time scales. The restriction to one spatial dimension permits representation of a wide range of length and time scales, including molecular processes, in a computationally affordable manner. In this seminar, the mechanics of ODT will be described in detail, and several representative calculations will be discussed. In addition, the application of ODT as a sub-grid-scale model in a large eddy simulation (LES) of channel flow will be presented.
