Class
    Foam::PatchFlowRateInjection
 
Group
    grpLagrangianIntermediateInjectionSubModels
 
Description
    Patch injection, by using patch flow rate to determine concentration and
    velocity.
 
    User specifies:
      - Total mass to inject
      - Name of patch
      - Injection duration
      - Injection target concentration/carrier volume flow rate
 
    Properties:
      - Initial parcel velocity given by local flow velocity
      - Parcel diameters obtained by distribution model
      - Parcels injected randomly across the patch
