With the model, the importance of suitable solution and air
flow rates can be highlighted. According to the simulation results,
it has been found that if the solution flow rate is too low, the effective
interfacial area can be reduced significantly due to the film
breakdown. If the air flow rate is too high, it is possible for the
air to carry over the liquid drop, which will be a big threaten to
the indoor environment. Therefore, the model can be an effective
way to predicate the optimum flow rates of the solution and air
in advance.
