Developing New Generation of Models for Turbulent Flows.
Abstract
The goal of the study was to generate, from a simple set of rules, a stochastic signal in space-time that would closely resemble the real turbulent data. This goal has been achieved and the work is reported in a journal article. The paper explains the principles and deals with one-dimensional signals whereas the thesis chapter deals with three-dimensional signals. These synthetic signals possess most of the statistical properties of real turbulence, and have been used as initial conditions in a direct numerical simulation of homogeneous turbulence. A comparable scheme was attempted for wall-bounded flows, and the principal hypothesis relating to this attempt was successfully verified in a high-Reynolds-number turbulent pipe flow, and a moderate-Reynolds-number turbulent boundary layer.
