Does anyone know what xyAngle, zAngle and umbrellaAngle in multiHoleInjectorProps dictionary below mean?
Is the 'direction' not required? Then how the injection direction is determined?
position (0.0097 0.028 0.01);
Thanks in advance,
The direction of the injecor is defined via the xy and z angles.
The spray is injected around this direction with the umbrellaAngle
spread around the full circle with the angleSpacing angles
Thanks for the reply.
I would like to set the injection direction to be in +z direction. With unitInjector, I will set: direction (0 0 1);
How can I do the same with multiHoleInjector? I can set zAngle = 0, but I've to specify a value for xyAngle, which makes the direction to be not purely in +z direction.
One more, Is there any relationship between umbrellaAngle and innerConeAngle/outerConeAngle which is in the hollowConeInjectorCoeffs dictionary? Graphical explanation will be highly appreciated.
if you set zAngle to 0 (or 180) the value of xyAngle wont matter.
The umbrellaAngle is the angle between the individual sprays along the injector-direction.
The inner/outer cone angles are the angles of an individual spray.
angleSpacing is the angles between the spray centerlines in the plane perpendicular to the injector-direction.
I use the rhoPisoTwinParcelFoam to investigate a particle-laden gas flow.
I want to calculate the total particle number across a cell surface in certain time.
And then I can get a particle flux for this cell face by N/(t*A),
N, the total particle number across the cell surface;
A, cell surface area.
I have poor knowledge about C++.
May you give me some help?
Thank you very much!
