| Research Abstract |
A new efficient and accurate numerical method for computation of passive scalar transport in turbulence was developed for the massive parallel machine and applied to the analysis of the anomalous fluctuations of the scalar. It is found that the scaling exponents of the scalar structure functions are not universal. Effects of the spatial dimension on turbulence was also studied. When the dimension is increased as 3, 4, and 5, the compressible motion in one direction becomes dominant over the motion in other directions.
