Cone cylindrical injection submodel that extends the 2D disc coneInjection
model, implemented in lagrangianIntermediate library, into 3D. This allows
better handling of the Lagrangian data especially when lots of parcels are
injected on the 2D disc that occasional solver crashes were reported.
In the new model, computational parcels are randomly injected from cylinder
of fixed height. The parameters for position, direction, cone
angles, and disc inner and outer diameters are all preserved for the new
model, while the parameters hCylinder and offsetCylinder are required
to set the cylinder height and offset from injector position.
Therefore, instead of injecting parcels over a disc (i.e. 2D surface), they are
introduced randomly within a 3D finite volume cylinder.
An artistic illustration of the cylindrical injection model is depicted in the following figure. Further details are found in [1]

The class ConeCylinderInjection implementing the present model is in the same
level as ConeInjection class, i.e. they both inherit from templated
InjectionModel.
-
Compile the library by executing
Allwmake -
Link the library during solver runTime. This is achieved by adding the following to
system/controlDictof the simulation case directory.
libs
(
"libconeCylinderInjection.so"
);
- Choose cylinder injection model from the corresponding subdictionary in
constant/sprayCloudPropertiesas in the following example.
