Abstract

The turbulent vortex shedding flow past a two-dimensional square cylinder at Re=2.2×104 (test case LES2) was analyzed by Large Eddy Simulation using various dynamic subgrid-scale (SGS) models [1–5]. The types of SGS model used are as follows: the static type of conventional Smagorinsky model (S model, eqns.(l) and (2) in the Appendix (case 1)); the Dynamic Smagorinsky model (DS model, eqn.(6) in the Appendix (case 2)); the Dynamic Mixed model (DM model, eqn.(10) in the Appendix (case 3)); and the Lagrangian Dynamic Mixed model (LDM model, eqn.(16) in the Appendix (case 4)).
