Hello All,

In my case, I want to create a patch for injecting particles. This, I am able to do using createPatchDict on the boundary faces.

But, I want to have this injection patch interior of my domain. I could not achieve this using createPatchDict as it creates patches on existing boundary faces.

I request you to please let me know if there is a way to create a patch inside the domain.

Thanks & Regards,
vidyadhar

Don't ask the same question three times... You're wasting our times.

Have a look at "CellZoneInjection" and "cellSet"s.

Dear Kevin,
Thank you for the reply.
I tried to construct the cellZoneInjection Model following your suggestion.
I am facing the following problem. I request you to help me solving this problem, if possible. (I am using "Caelus" which is very much similar to openFoam)

Part-Output of the log file
Constructing particle injection models
Creating injector: model3
Selecting injection model cellZoneInjection
Constructing 3-D injection
Selecting distribution model fixedValue
cell zone size = 3610
cell zone volume = 6.041191959e-09
--> CAELUS Warning :
From function CML::CellZoneInjection<CloudType>::updateMesh()
in file lagrangian/intermediate/lnInclude/CellZoneInjection.hpp at line 397
Number of particles to be added to cellZone particle_INLET1 is zero


The injection model in my particle Cloud properties file is like below:

model3
{
type cellZoneInjection;
cellZone particle_INLET1;
SOI 0.0112; // Start Of Injection
flowRateProfile constant 1; // Flow rate profile relative to SOI

massTotal 3.4746e-08; // Total mass injected over injection duration
parcelBasisType mass; // How are the number of particles calculated
duration 1.2; // Duration of injection. NOTE: set to 1 for steady state
U0 (0 0 0.04175); // Initial parcel velocity

numberDensity 500; //Number density of particles in cell set (effective)
nParticles 500; //I am trying these options to check if particles are getting injected or not
nparcels 500;
//I am trying these options to check if particles are getting injected or not // parcelsPerSecond 4167; // Number of parcels to introduce per second

sizeDistribution
{
type fixedValue;
fixedValueDistribution
{
value 0.48e-03;
}
}
}

I have used toposetDict to create the cellZone:
actions
(

{
name particle_INLET1cellSet;
type cellSet;
action new;
source boxToCell;
sourceInfo
{
box (-0.0036 0.0012 -0.0125)(-0.0012 0.0036 -0.0115);
}
}

{
name particle_INLET1;
type cellZoneSet;
action new;
source setToCellZone;
sourceInfo
{
set particle_INLET1cellSet;
}
}


I am missing some keyword(for adding no.of particles to the cellZone) in the injection model.

Thanks in advance,
Regards,
vidyadhar

You can create baffles and then use one of the two cyclic patches as an injection patch

How to create baffle?
