Scale Adaptive Simulation (SAS) is used to study the flow around a circular cylinder at Reynolds number 3 900. SAS predictions are compared with the popular Detached Eddy Simulation (DES) and existing experimental data. The effect of grid resolution and spanwise domain size on SAS model performance are systematically analyzed, time-averaged turbulent statistics and instantaneous distributions of the von Karman length scale in the wake region are discussed in detail. It is concluded that the recirculation length of SAS is smaller than that of Large Eddy Simulation (LES) under the same grid resolution, indicating an earlier onset of instability in shear layer. Velocity magnitude inside the recirculation bubble increases and the peak value of Reynolds stress decreases with grid refinement for SAS simulation, which are in good agreement with the experimental data of Lourenco & Shih. Additionally, changing the spanwise domain size with the same resolution has little effect on SAS predictions. The investigations on the influence of grid resolution and the spanwise domain size on SAS model performance can provide guidance for industrial applications of the SAS method in future.
