Verification and validation for turbulent mixing Original Research Article

Verification and validation constitute a relatively new requirement for numerical analysis. It is one which results from the growing practical use of computation as a basis for engineering decisions. While a number of procedures have been proposed for these tasks, their application to the more difficult cases remains a research issue. Here we explain methods developed by ourselves and collaborators for verification and validation of simulations for chaotic, multiscale flows, specifically for turbulent mixing simulations.
