The importance of visualizing multivariate volume data from turbulent combustion simulations is discussed. Direct numerical simulation (DNS) of a turbulent non-premixed flame with the detailed chemistry shows how the resulting visualizations present information, which are previously unseen and provide new understanding and validation of such simulations. DNS can fully resolve a turbulent combustion process's finest spatial and temporal details and focus on a particular physical aspect of the process. Visualization's major roles in the DNS of combustion will be to provide qualitative understanding of the underlying combustion phenomena and guide combustion scientists toward regions requiring more quantitative analysis. The ability to simultaneously visualize multiple variables is essential because combustion is a multiscalar problem with intricate coupling between reactive scalars and the flow field. The techniques are also useful in guiding qualitative understanding and extracting knowledge from combustion data.
