In this paper, a three-dimensional axial symmetrical model of laser cutting is established by adopting N–S equation and shearing-stress transport k-ω turbulent model. Numerical simulation is carried out to analyze the flow field of shield gas inside a cut kerf; the results include velocity and pressure distribution and mass flow rate. The effects of oxidation on flow field are examined, and the formation of gas flow separation and vortex are predicted. The results show that the gas flow structure in the kerf is directly affected by the reaction between iron and oxygen in the case of laser-oxygen cutting.
