N2 - In order to investigate the influence of gas volume flow rate on length of helium plasma jet, by establishing cylindrical three-dimensional computational domain, we simulated three-dimensional image of gas boundary, plasma jet velocity image, velocity vector image, and gas mass fraction under different volume flow rates. Furthermore, the simulation results were verified by experiments. Considering the influence of turbulence under high volume flow rate condition on plasma jet discharge, we solved the Navier-Stokes, RNG k-ε turbulence equation and species mass transportation equation. The simulation results showed that, when the flow was laminar, the axial helium velocity and mass fraction increased with the gas volume flow rate, which was consistent with experimental results that helium plasma plume length increased with the gas volume flow rate. When the flow was turbulent, the axial helium mass fraction decreased, which was in agree with experimental results that helium plasma plume length decreased with increasing the gas volume flow rate.
