Answer» The correct answer is (a) BOUSSINESQ hypothesis and Prandtl MIXING length model To elaborate: The Smagorinsky-Lilly (Sub-Grid-Scale) SGS model is built on the Prandtl mixing length model and MODELS the SGS eddy viscosities. It uses the Boussinesq hypothesis to assume the effects of the SGS EDDIES.
