The immediate goal of this work is to test the performance of the dynamic subgrid-scale (SGS) model and some of its possible variants in incompressible channel flow with passive scalars and with Boussinesq buoyancy. The large eddy simulation (LES) results with the dynamic SGS model will be compared with low Reynolds number direct numerical simulation (DNS) data and with higher Reynolds number laboratory data. The consequences of implementing the dynamics SGS model at a local level rather than using globally averaged coefficients, which would be useful for applications with more complex geometries, will also be explored. A longer range goal of this work will be to test the performance of SGS models in the LES of flows with more complicated physics (e.g., rotation and density stratification), applicable to geophysical and astrophysical systems.
