   This case provides a simple demonstration of the calculation of
   residence time for plane turbulent channel flow over a cavity.
   The channel is 0.5m high by 3m long, and the cavity, which is
   located centrally beneath the channel, is 2.5m high by 1.5m wide.
   Fluid enters with a velocity of 1m/s corresponding to a Reynolds
   number of 3.24E4. The turbulence is represented by means of the
   standard k-e model.

   The procedure for calculating the residence time corresponds
   closely to the way residence times are measured in practice:

   1) obtain the steady-state solution for the hydrodynamics.
   2) perform a restart calculation from these solution fields so
      as to make a transient analysis for a single scalar quantity
      C1, which enters in a short pulse and is then convected out
      of the solution domain.

   The spread in time corresponds corresponds in part to the
   convective and diffusive mixing processes; but numerical
   diffusion is also present. The residence time is determined by
   monitoring the exit concentration with time, and noting when
   the exit value reaches a maximum. The PHOENICS simulation
   predicts the expected residence time of 3s, as may be seen
   on inspection of the PROFIL plot at the end of the RESULT
   file.
