摘要

A two-equation turbulence model that can adjust itself from RANS to LES regimes is constructed using the renormalization group. When the grid-spacing gets too coarse for LES, the model tends to a RANS model. In well-resolved regions the model results in a LES subgrid-model. The renormalization group procedure leads to transport-equations that are dependent on the filterwidth and contain no adjustable constants.
