Abstract Applying the similarity theory based upon the behaviour of the supersonicoxygen jet of 2.12 and 1.465 Mach respectively and upon its interaction withthe bath, certain simulation tests for 50-ton LD converter have been carried out. Incase of geometry and boundary condition similarities, a new test, the so called"lower density simulation", has been proposed to realize not only the jet dynam-ics but also its interaction with bath. In all, five tests simulating the jet dynam-ics behaviour under various conditions, its interaction with bath, the inlluenceof fluid dynamics on rate of carburization in bath, etc. were conducted. The rel-iability of such lower density simulation tests for LD converter was subjected totheoretical analysis and further verified by experimental results obtained by NACA.
