title = "Spectral element-RNG simulations of turbulent flows in complex geometries",

abstract = "Renormalization Group Theory (RNG) modeling techniques are combined with spectral element discretization procedures to formulate an algorithm appropriate for simulating high Reynolds number turbulent flows in complex geometries. Three different approaches of modeling are followed based on RNG algebraic, differential K-epsilon, and subgrid-scale models for the turbulent viscosity. Results obtained for the fully developed channel flow, and for the separated flow over a backwards-facing step suggest that all three formulations are suitable for turbulent flow simulations.",
