i am confused about the definitions and uses of the configuration of both the unitInjector and the commonRailInjector in the dieselFoam/dieselEngineFoam cases. position and direction are self explanatory, but ...

assuming i start with some diameter of particle injected, increasing the mass drastically increases the amount of injected material per unit time in the simulation -- the definition of mass also seems to limit the total amount of mass injected into the system before the injector is turned "off". what am i really defining here? shouldn't the mass of each particle be nicely defined by its radius and the density of the species being tracked? (C7H16 here ...)

nparcels also confuses me ... an increase there increases the number of parcels injected per unit time in the simulation, but has no effect whatsoever on the mass injected per unit time.

i assume Cd refers to the stokes law correction term in the lagrangian? what is X?

how is massFlowRateProfile defined?

sorry to as so much at once ... i just can't seem to find the appropriate documentation.

thanks,
