Stirred Tank Modeling Using LES

In turbulent flows, large scale eddies with coherent structmes are primarily responsible for the mixing of passive scalars. The large scale eddies embody themselves in the form of identifiable and organized distributions of vorticity. In addition, the mixing process involves all mechanisms typically found in vortex dynamics, such as stretching, breakup, concatenation, and self-induction of

When performing such LES calculations, it is advised to visualize the results by creating flow field images after every time step. These can then be used to create animations. Similarly, statistical data can be obtained by creating monitor points or lines in the domain and saving important variables in these locations. The time series that are obtained in this manner can be analyzed further using standard statistical and signal analysis techniques.
