Six planar supersonic jets are computed by compressible large-eddy simulations (LES) using low-dissipation schemes. At the exit of a nozzle of height h, they are ideally expanded and have an exit velocity ue, yielding a Mach number of Me = 1.28, and a Reynolds number of Reh = ueh/ν = 5 × 10 4 . Four jets impinging on a flat plate at distances L from the nozzle lips ranging from 3.94h up to 9.1h, with an angle θ between the jet direction and the plate of 90 degrees, are first considered.
