At the Iron and Steel Institute of Z.I. Nekrasov of NASU, the followers of S.I. Semykin continued their research on the use of high-voltage electrical activation of the oxygen flow during blowing in converters in order to improve physicochemical processes. A high-voltage discharge is formed at the output of a coaxial slot nozzle, which affects the hydro-gas dynamic indicators of the gas – environment interaction. This was the purpose of the research. According to the results of a low-temperature and numerical study (in the ANSYS Fluent) it was established that the properties of the experimental flow are formed under the influence, first of all, of the design with the formation of not typical flow shape at the beginning of the flow, different from those known for a cylindrical nozzle, with higher velocities. This corresponds to the more rigid blowing noted according to the results of low-temperature modeling.
