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 definemodelssolversaxisymmetric 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 
Re: swirl flow
ihave some experimental results of swirl flow when modeled same in fluyent i am not getting required pressure drop. can you help me.

Re: swirl flow
What discretization scheme and turbulence model are you using?

Re: swirl flow
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 ..

Dear Tom If you can allow me to attach me on your mail the brief details i can describe the same. thank you

swirl flow.....
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? my email id :shshiva17@gmail.com 
I also have this problem

need help for ke turbulence model,RNG
PROPELLERrotation 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 KE. domain with dia 4d, length 7d, d=1.4m. material water_liquid.

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