TITLE   : VEHICULAR EXHAUST DISPERSION IN RAINFALL
  BY      : S Zhubrin - CHAM-MEI
DETAILS :
-   This case is a part of a project to predict turbulent and
      two-phase flows at the town scale.
 -   It is concerned with the rainfall in the street canyon
      between one elevated building and its low-rise neighbouring
      block.
 -   The pollution is a simulated by inter-phase transport from
      gaseous to liquid phase, governed by specification of
      interphase transfer coefficients and
 -   PLANT instructions provided in Group 10 make the special GROUND
      codings.
 
    Further details of PLANT:
-  PLANT is a PHOENICS add-on which allows users to change
     the coding within certain GROUND groups and sections using
     PIL instructions in the Q1 file.
 -  PLANT can include GROUND coding for non-linear property
     correlations, interphase transport features, initial fields,
     non-linear source laws and output control calculations.
 -  PLANT is intended for use by those with a need to include
     GROUND routines but who either lack the necessary FORTRAN
     knowledge or who wish to same time by placing the necessary
     commands in the Q1 file
 -  PLANT adds the required coding into GROUND and recompiles
     the EARTH executable before starting the run.
 -  PLANT is included in PHOENICS 1.4 Shareware.
