DISPLAY
This case is a part of a project to predict turbulent and
two-phase flows on an urban scale. It concerns rain-fall in a
street canyon between one elevated building and its low -rise
neighbour block.
The pollution is affected by inter-phase transport from gas to
liquid phase governed by specification of values of interphase
transfer coefficients and PHI differences between the phase$
s.
PLANT instructions are provided in Group 10 make create
special GROUND codings
ENDDIS
PLANTBEGIN
** Instruct PLANT to code the inter-phase transfer coefficients
and PHI differences between the phases.
