Abstract

The flowfield of a turbulent supercritical liquid-oxygen/methane mixing layer is computed using two-dimensional direct numerical simulation. A priori analyses of the subfilter velocity-velocity and velocity-scalar covariances are performed against the dynamic eddy-viscosity type models. The models are evaluated at different filter sizes to gain understanding on the performance of these models at high filter sizes. The relevance of subfilter scalar-scalar covariance terms and the lack of modeling efforts in this direction are also highlighted.
