Hi everyone
I'd like to perform a simulation of a jet of burning kerosene in an duct.
Could someone help me about the meaning of the parameters in the injectorProperties dictionary (in particular the Cd and nParcels parameters)?
I want to specify a constant mass flow rate of liquid from the injector and I would like to have some control on the liquid particle dimension injected.

unitInjectorProps
{
position (0 0.0995 0);
direction (0 -1 0);
diameter 0.00019;
Cd 0.9;
mass 6e-06;
temperature 320;
nParcels 5000;
......

Thank you
Antonio

I have another doubt
I suppose that the models for drag, evaporation ecc
are related to particles dimension. I haven't understand the relation between parcel and particle for what concern dimensions.
When a parcel is injected (according to the specified massflowrate and nparcel) what are its characteristics? What is the diameters of the particles that are represented by the parcel?
