Mixing and Reactions in Turbulent Flows
3. Statistical description of turbulent mixing
In this Chapter, we will derive the governing equation for a reacting scalar i
Approach to Chaos 0. Introduction There are two major reasons for studying non-linear systems. The first and most basic is that the equations of motion of almost all real systems are non-linear. The s

Free thin shear ows
In this Chapter, we will discuss a large class of ows called thin shear ows. We will focus
