  This run examines how the flow around a chimney intermingles
  with the effluent from it. A concentration equation is solved so
  as to determine the rate of dilution of the effluent.
    Interesting variants include:- changes to the chimney shape;
  changes to the flow rate through the chimney top; and changes
  to the wind velocity.
