Class
    Foam::PatchFlowRateInjection
 
Description
    Patch injection in which the quantity of particulate material introduced is
    specified as a fraction of the carrier flow rate.
 
    User specifies:
      - Name of patch
      - Injection duration
      - The particulate/carrier volume or mass ratio
      - The number concentration of parcels
 
    Properties:
      - Initial parcel velocity given by local flow velocity
      - Parcel diameters obtained by distribution model
      - Parcels injected randomly across the patch
