Default blob injection and patchInjection

vishal_s is on a distinguished road

I am trying to do a Lagrangian spray modelling. In the aachenBomb tutorial, the injector type is coneNozzleInjection. I want a blob injection, were the droplets are injected at a fixed diameter.

First of all, I would like to know is "patchInjection" same as blob injection. Secondly, considering using patchInjection, if I mention the inlet fluid velocity of the same patch in 0/U and massFlowRate in the injectionModels, why I need to give velocity of the droplets again?

I am using OF-2.2.2.

Struck with this problem, any help is really appreciated.
