Default swirl flow

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

regards rvndr

What discretization scheme and turbulence model are you using?

Hello Amit, I am also modeling gas turbine combustor with all of the flow features using fluent. May be we can share the information/results for better undrestanding of flow physics ..

Regards, Gaurav

Hi frns,,,,
Am also doing seirl flow in combustor model but i sonno how to calculate the components like axial,,circumferential i.e,,,,,swirl velocity,,,,,,i know my swirl no and velocity,,,,,if u know any calculation theory regarding this plzzz help me?

PROPELLER-rotation clockwise.
domain:::::inlet was considered of distance of 3D from mid of chord of root
section and outlet is considerd upto a dist of 4D from axis of hub.
at J=O.45, N=783.6RPM, Va = 8.23m/s
It is steady flow, turbulent model- RNG K-E.

domain with dia 4d, length 7d, d=1.4m.
material- water_liquid.

Hey Im new to CFD, and im simulating combustion chamber of a gas turbine. Im using 2D axisymmetric. I have mention the swirl number and inlet velocity. How do I calculate the swirl velocity??? Please help. Im new to this. Any help will be appreciated. Please.

Hi, do you have a copy of this book: gas turbine combustion by arthur lefebvre? I think it would be helpful to you.
