Hi Junichi, In both the cylinder and SD7003 cases in the paper you cited we used an Implicit LES (ILES) approach. With ILES we rely on the inherent numerical dissipation of the flux reconstruction approach at high frequencies to act as an implicit sub grid scale model for the un-resolved scales. Therefore, there is no explicit SGS model currently implemented in PyFR. You can read more about ILES using flux reconstruction here: "B.C. Vermeire, S. Nadarajah, P.G. Tucker, Implicit large eddy simulation using the high-order correction procedure via reconstruction scheme. Int. J. Numer. Meth. Fluids 2016; 82:231–260". The introduction has a general discussion about the approach.
