Abstract : Incompressible axisymmetric swirling flow with open boundaries is studied by means of direct numerical simulation (DNS). The effects of viscosity and external axial pressure gradient near critical swirl number are investigated. The solution branches obtained from DNS match the bifurcation diagrams from previous theoretical and numerical studies and extend their results.
