Simulations of Turbulent Mixing
Turbulent flows, which are very challenging to predict, include such important practical problems as how well different chemical species will mix and sometimes react in a fluid. This 3-D volume rendering shows the dissipation rate related to the spreading of a contaminant that is carried along passively (without reacting or burning) in a turbulent flow, computed on the San Diego Supercomputer Center's (SDSC) DataStar supercomputer using a detailed 2,0483 grid that divides the domain into some 8 billion parts. The very high resolution of these direct numerical simulations reveals the complex sheet-like topology of high-activity regions where the most intense turbulent mixing and chemical reactions occur. The research was part of an NSF-supported collaboration between computational scientists from SDSC at UC San Diego and researchers in Professor P.K. Yeung's group at Georgia Tech.
