    Abstract

    We applied dynamic inverse modelling to large-eddy simulation of the temporal mixing layer. Smagorinsky’s model is adopted as base model and the results are compared to the standard dynamic eddy-viscosity model as well as filtered DNS results. The difference between the results of the two models for the present application is found to be small. This is explained by performing a detailed sensitivity analysis with respect to the dynamic coefficient, which appears to hint towards a ‘self-restoring’ response underlying the observed robustness.
