Turbulent flows, which are very challenging to predict, include such important practical problems as how well different chemical species will mix and possibly react in a fluid. This 3D volume rendering shows the solar dissipation rate for a weakly diffusive passive contaminant computed on SDSC's Datastar supercomputer on a 2048^3 grid. The very high resolution of these direct numerical simulations in an SDSC SAC collaboration with NSF-supported research by P.K. Yeung and his group at Georgia Tech reveals the complex sheet-like topology of high activity regions where the most intense turbulent mixing and chemical reactions occur.
