CFX or Fluent for Turbo machinery ?

Posted May 27, 2011 at 03:03 by Far

First I would like to say that both flow solvers tend to provide the similar results if the mesh is of good quality and has appropriate no.of nodes and yplus values.

Therfore the first and the most important rule is to make, in any simulation of turbo machinery in particular and external flows in general, high quality mesh with all appropriate parameters e.g. yplus.

Now lets come to the difference

1. CFX has good turbulence models, although after merger...

Atmosphearic flow problem.

Posted April 4, 2011 at 05:37 by vishal

Hi All,

I know its really painful to find correct formulas for calculation of k and Epsilon values, If any of you are dealing with atmosphetic flows. (Exponential valocity inlet or power law). I would recommend to "atmBoundaryLayderInlet" conditions located at



OpenFOAM1.7.1/scr/turbulanceModels/incompressible/RAS/derivedFvPatchFields/atmBoundaryLayerInletEpsilon/atmBoundaryLayerInletVelocity.c file.

over list of values at inlet and...
