Sig Turbomachinery / Tutorials

Here you can add turbomachinery tutorials to the standard distribution, or to the turbomachinery developments of OpenFOAM.

Whenever possible, the tutorials should be included in the basic structure of theOpenFOAM Wiki, and here you can add links to those tutorials that are of interest to the turbomachinery field.

3.1 Cylindrical Coordinate Systems

The example requires that you have a mesh and a velocity field U, and that you have defined inletPatchID. You also need to do #include "cylindricalCS.H". If your base code writes out the velocity field U you can then visualize the radial, tangential and axial coordinates as U at the inlet patch using for instance paraFoam. The example was developed for OF1.3.

//Test of cylindricalCS

//Find the Cartesian positions at the patch const fvPatchVectorField& cartFaceCentres = mesh.Cf().boundaryField()[inletPatchID];

//Put the results in U at the patch so that you can visualize the result fvPatchVectorField& CCSin = U.boundaryField()[inletPatchID];

//Define your cylindrical coordinate system cylindricalCS ccs ( "ccs", vector(0, 0, 0), //center point of ccs vector(0, 0, 1), //axis of ccs vector(1, 1, 0) //base axis for cylindrical angle );

//It doesn't seem to be possible to do the whole field at once, so //loop through all the patch faces and set the radial, tangential and //axial position forAll(CCSin, facei) { CCSin[facei] = ccs.toLocal(cartFaceCentres[facei]); //Make sure that you have only positive angles and that the //angle is zero at the base axis: CCSin[facei][1] = CCSin[facei][1] + neg(CCSin[facei][1])*360; }

//You can also look at a single cylindrical component, here radial: Info << "ccs.toLocal(cartFaceCentres[0]).component(vector::X)" << endl; Info << ccs.toLocal(cartFaceCentres[0]).component(vector::X) << endl;
