Abstract：Objective:To verify the feasibility of local diffusion oxygen enrichment by studying the effects of different oxygen supply positions and oxygen jet angles on the desktop on the working breathing zone in sitting position.Methods:The effects of different initial conditions on the increase rate of oxygen concentration in the suction zone were compared by detecting the oxygen concentration distribution in the working breathing zone in sitting position under different oxygen supply terminal positions and oxygen jet angles on the desktop.Results:Different oxygen supply positions and oxygen jet angles had different effects on the increase rate of oxygen concentration in the suction zone on the desktop.Conclusion:By adjusting different initial conditions,local diffusion oxygen enrichment in the working breathing zone in sitting position can be achieved.
