Setting rotating frame of referece.

RPFigueiredo · October 27, 2014, 10:19

Hello!

I'd like to ask a few insights on my setup for a rotating impeller,as seen on the image:

http://s13.postimg.org/hzakt4dmf/image.jpg

Let's go over each domain and boundaries/interfaces:

DOMAIN ANEL

Continuous fluid, 1MPa reference pressure, Stationary, Shear Stress Transport

Anel_walls: non slip smooth wall
Outlet: Average static pressure 7.6MPa/PPres. Profile Blend 0.05
Domain interface 2 side 2: interface, conservative interface flux

DOMAIN DUTO

Continuous fluid, 1MPa reference pressure, Stationary, Shear Stress Transport

Duto_walls: non slip smooth wall
Inlet: Mass Flow rate 14kg/s/Normal to boundary/Zero gradient turbulence
Domain interface 1 side 1: Conservatice Interface Flux

DOMAIN IMPELIDOR

Continuous fluid, Reference 1MPa, Rotating -24000rpm about global Y

Domain interface 1 side 2: conservative interface flux
Domain interface 2 side 2: conservative interface flux
Imp_walls: Frame type rotating, no slip smooth wall

INTERFACES

Domain interface 1: General connection, Frozen rotor, Pitch ratio 1
Domain interface 2: General connection, Frozen rotor, Pitch ratio 1

About solver control, timestep is set to physical, 4.167e-6s. So, is there something too wrong? bacause the solver refuses to run over iteration 1! Any input would be appreciated.

Thank you in advance!

Please post your output file.

Also note that it appears you could model this with a single rotating domain, and no stationary domains. Then there is no need for interfaces.

I realize I could avoid the interfaces. I tried it with the single RFR, but it wouldn't work, so I added the stationary as I will eventually have to model the volute (once I figure out the issue).

Here's the out file:
