In order to clarify the effects of gas temperature around a jet on the characteristics of supersonic jet in LD converter, theoretical analysis on the transport phenomena of supersonic jet is proposed in this work.
Axial and radial distributions of velocity, temperature, mass fractions and density for turbulent compressible free jet are determined under consideration of the mixing in a jet and the flow rate of gas entrained from the surrounding. It is found that the effects of gas temperature around a jet on these distributions are remarkable.
Moreover, relations between the operating variables (axial distance from exit of nozzle and back pressure) and the behaviour of supersonic jets are obtained from numerical calculations with the aidof digital computer.
