Adding a source term to k and epsilon equation for buoyancy

rajeshkunwar · December 7, 2012, 09:53

Hi..

I am adding a term which is a function of density gradient and gravitational acceleration (g) to k and epsilon equation of compressible k-epsilon model. while compiling my new k-epsilon model, error comes as

In file included from mykEpsilon.C:268:0:
/home/rajesh/OpenFOAM/OpenFOAM-2.1.1/src/finiteVolume/lnInclude/readGravitationalAcceleration.H:1:5: error: ‘Info’ does not name a type

Pls help....

Hi,

It seems that there is some error in your readgravitationalacceleration.H file. The second error in your .C file also points to not being able to read properly. Make sure that the contents of the above mentioned .H file are correct.

I am also working on buoyancy driven flows. May I know how you are adding the source term for buoyancy to the k-equation?

I am also wondering how I can add buoyancy term into K and epsilon.

I found Gcoef in buoyantKEpsilon and I am trying to use it.
