In the future, state implementation plans and local
environmental regulations will need to consider
the energy consumption of control devices and not
just stack total emissions, as producing electricity
to operate control devices results in pollution where
that electricity is generated (Funk, 2010). Future
cyclone research will continue to focus on collection
effectiveness, especially for finer particulates,
but will also focus on minimizing energy costs. As
computing resources become less expensive and
CFD modeling becomes more sophisticated, increasingly
complex models will continue to contribute
to our still imperfect understanding. Yet numerical
simulation will always require validation trials that
test cyclones under conditions and loads as near to
the real world application as feasible. As methods
for quantification of particulate emission particle size
distributions become more affordable, the quality of
the data collected in these future trials should further
improve (Ray et al., 2000).
