The test setup has two nozzles, each connected to one of the two outlets of the diverter-type oscillator. The nozzles were of annular exit cross section and operated in anti-parallel. The investigation, focused on study of the temperature fields on a plane impingement wall visualized by thermochromic liquid crystals, revealed some unexpected effects.
