Inflow conditions for the large eddy simulation of turbulent boundary layers: A dynamic recycling procedure

The simulation of turbulent boundary layers requires quite detailed inflow information since the resolved flow is unsteady and three-dimensional. Rather than simulating laminar and transitional regions arising near a leading edge, it is often more computationally efficient to formulate a fully turbulent inflow condition. To date, three types of methods for creating appropriate inflow conditions have been suggested: the random fluctuation method (Rai and Moin [1]), the matching database method (Schlüter et al.[2]), and the recycling and rescaling method (Spalart [3] and Lund et al. [4]). The classification of ∗ Corresponding author Email address: [email protected] (Kunlun Liu).
