For the simulation of a supersonic turbulent boundary layer, two methods of generating synthetic turbulent inflow data are compared, namely the Random Fourier Modes (RFM), and the Synthetic Eddy Method (SEM). The first one relies on theoretical properties of turbulence, whereas the second one is essentially based on empirical informations. The adaptation distance needed to recover a realistic wall turbulence is smaller than 10 initial boundary layer thicknesses for the SEM inflow, and roughly twice longer for the RFM inflow. A correct prescription of the phase information is seen to be a key element to efficiently generate a sustained wall turbulence.
