The large-scale coherent structures present in high-speed turbulent jets are modelled for round nozzle twin-jet configurations at supersonic conditions based on industrial-type RANS simulations and plane-marching parabolised stability equations (PSE). These relatively inexpensive models predict jet-jet coupling, oscillation modes and mixing noise radiation directivity in agreement with experimental observations.
