### Event Description:

Title:

** Research program on turbulence modeling and simulation at the UNM Department of Mechanical Engineering**

Abstract:

This presentation is an overview of research projects conducted at the UNM ME Department in the area of turbulence modeling and simulation that can benefit from collaboration with faculty and students from the UNM Department of Mathematics and Statistics. Some of the projects to be discussed are

- modeling of the probability density function of a turbulent flow field with the truncated Gram-Charlier series expansions;
- data-driven modeling of physical processes that occur in turbulent flows;
- analysis of the Reynolds-averaged Navier-Stokes (RANS) equation sensitivity to modeling errors;
- generation of reference data for model validation using direct numerical simulations (DNS);
- analysis of uncertainty in DNS data.

Recently discovered fundamental issues associated with RANS-based modeling and DNS will be discussed in the light of how these roadblocks can be turned into stepping stones towards advancing our understanding, description, and prediction of turbulent flows.
