swirling Flows in fluent 5.0
Dear friends, Here is one more problem of mine.I have been working on fluent and at the moment i want to see how it responds to swirling flowsin combustors.But i am not able to find appropriate inlet condition input where i can give both flow rate and swirl at 45 degree as inlet boundary condition.If velocity is specified by Direction Vector i.e. X,Y,Z component of Flow direction,what values should i give to achieve swirl When Swirler vanes are making an angle of 45 degree with x axis in axissymmetric combustor.

Please let me know the Procedure if anyone of you Know it.

Re: swirling Flows in fluent 5.0
set the inlet boundary type to mass flow, and use mass flux as the specification method. You can then set a mass flow profile i.e. swirl with a direction vector. see p6-37 vol 1 of the fluent users guide
