Hi,
I am trying to figure out the correct setup for the coneInjection props of a spray of water into air.

Say I want to inject a mass of 0.02296 kg water of 30 micron droplets in 1 second through 2 injection points at 22 Celsius , besides specifying in "reactingCloud1Properties" the temperature in constantProperties part, the model should look like this?

model1
{
type coneInjection;
SOI 0.0; //start of injection
duration 1; // seconds
// injector(s) position(s)
positionAxis
(
((0 -0.125 0) (1 0 0))
((0 0.125 0) (1 0 0))
);


// parcelBasisType fixed;
// nParticle 2e4;

parcelBasisType mass;
massTotal 0.02296; //2 injectors * 1 s * 41 l/h(Water) = 2 * 0.01479
parcelsPerInjector 1e4; // 10000 parcels * 1s

flowRateProfile constant 1;
Umag constant 11.4;

thetaInner constant 0; // full cone
thetaOuter constant 84;

sizeDistribution
{
// type RosinRammler;
type fixedValue;

RosinRammlerDistribution
{
minValue 5e-04;
maxValue 0.0035;
d 7.5e-05;
n 0.5;
}

fixedValueDistribution
{
value 30e-6;
}

}
}

The mass that I am getting in the simulation does not seem to match the total Mass that I am specifying...does this parcelPerInjector have some influence on the results? or my problem lies elsewhere... (I am using reactingParcelFoam of OF2.3.0)

any help much appreciated.
