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 GroovyBC.
Here are some threads which might be useful for you people..

you can actually modify the formula in "atmBoundaryLayderInletvelopcity" as per needed and compile for usage.
Cheers,
