hey there, Im a bit of a newby to Openfoam, struggling to validate my results for Naca 0012 at 10deg angle of attack.
im not sure if it's a meshing or BC issue but looking at the velocity profile of the wake it seems way off. any help will be much appreciated!! primaraly interstead in the tip vortex Code:
FoamFile { version 2.0; format ascii; class volScalarField; object k; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // #include "include/initialConditions" dimensions [0 2 -2 0 0 0 0]; internalField uniform $turbulentKE; boundaryField { #include "include/fixedInlet" outlet { type inletOutlet; inletValue $internalField; value $internalField; } "wing_1.*" { type zeroGradient; } #include "include/frontBackUpperPatches" } Code:
FoamFile { version 2.0; format ascii; class volScalarField; location "0"; object nut; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 2 -1 0 0 0 0]; internalField uniform 0; boundaryField { frontAndBack { type calculated; value uniform 0; } inlet { type calculated; value uniform 0; } outlet { type calculated; value uniform 0; } lowerWall { type nutkWallFunction; value uniform 0; } upperWall { type calculated; value uniform 0; } "wing_1.*" { type nutkWallFunction; value uniform 0; } } Code:
FoamFile { version 2.0; format ascii; class volScalarField; object omega; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // #include "include/initialConditions" dimensions [0 0 -1 0 0 0 0]; internalField uniform $turbulentOmega; boundaryField { #include "include/fixedInlet" outlet { type inletOutlet; inletValue $internalField; value $internalField; } "wing_1.*" { type zeroGradient; } #include "include/frontBackUpperPatches" } // ************************************************************************* // Code:
FoamFile { version 2.0; format ascii; class volScalarField; object p; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // #include "include/initialConditions" dimensions [0 2 -2 0 0 0 0]; internalField uniform $pressure; boundaryField { inlet { type zeroGradient; } outlet { type fixedValue; value $internalField; } "wing_1.*" { type zeroGradient; } #include "include/frontBackUpperPatches" } // ************************************************************************* // Code:
version 2.0; format ascii; class volVectorField; location "0"; object U; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // #include "include/initialConditions" dimensions [0 1 -1 0 0 0 0]; internalField uniform $flowVelocity; boundaryField { #include "include/fixedInlet" outlet { type inletOutlet; inletValue uniform (0 0 0); value $internalField; } "wing_1.*" { type fixedValue; value uniform (0 0 0); } #include "include/frontBackUpperPatches" } // ************************************************************************* // Last edited by wyldckat; April 30, 2017 at 12:20.

Quick note: Part of the answer to this thread (regarding k-omega initialization) is being dealt on another thread: k and omega at inlet for k-omega SST
