Abstract In the present work, the behavior of oxygen flow in supersonic nozzles lance is analyzed by CFD and design changes to improve performance are proposed. The methodology involves the use of CFD in the design of the tip nozzle. The behavior of oxygen jet along the nozzle is analyzed, since the region of high pressure and low speed until the entrance to the supersonic condition at the output. The values obtained are compared to analytical results for ideal conditions and geometry changes to reduce losses are proposed. The behavior of the jet and its interaction with the environment are also investigated. The new geometries proposed are analyzed in order to maximize the jet speed.
