Abstract [en]

Oxygen cutting of steel is a process of oxidation at raised temperatures. A very high massrate of oxygen is needed. The exit velocity of the oxygen is often supersonic. Convergent-divergent nozzles of Laval type are used. The cutting gives rise to very high noise levels. Levels of up to 110 dB(A) at 1 meter distance from two burners have been measured at a steel plant. The central supersonic oxygen jet is surrounded by a burning coaxial jet. The noise source is a combination of the jet and the combustion. A reduction of the noise at the source is attempted by redesigning the nozzles used. This paper discusses the theoretical background and the experimental results relating to the redesigned nozzle.
