swirl flow

rvndr

hi friends

how to model a swirl flow.....in a 2D combustor with velocity inlet and pressure outlet as a boundary conditions.I tried by selecting

define---models---solvers----axisymmetric swirl flow.

Is this is the correct way.

if this is the correct way then how to calculate

1.Axial component of flow direction 2.Radial component of flow direction.

I know only inlet air velocity and swirl number for example (velocity 1m/sec and swirl number 0.3). Ofcourse mass flow also I know.

If there is any literature plz do help me

Thanks in advance
