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 |
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 k-e turbulence model,RNG
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. |

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