| Abstract: | The effect of gas flow on the helical instability is studied by using linear time perturbation theory in this paper, The corresponding equations and the boundary conditions are deduced. The marginal Maecker's number and the growth rate of the helical instability are given. Computational results show that the axial gas flow play the main role on the arc stability. |
