title = "A scale-adaptive variant of the Spalart-Allmaras eddy- viscosity model",
abstract = "A method is presented for introducing scale-adaptive capabilities into the SpalartAllmaras one-equation turbulence model that allows it to resolve large-scale turbulent flow features. Unlike detached-eddy simulation, scale-adaptive methods dynamically respond to the resolved turbulent content without an explicit dependency on the local grid size, and the compatibility of the relevant length scales makes it more resilient to modeled stress depletion. The formulation is based on existing scale-adaptive models, comparisons of the relevant length scales in boundary-layer flows, and the desire to preserve the existing steady RANS capabilities of the model when appropriate. Results are presented that demonstrate the capabilities of the scale-adaptive Spalart-Allmaras variant and are compared to results using traditional unsteady RANS and detached-eddy simulation.",
