An experimental study on the evaporation of a small
water droplet containing an additive on a heated,
polished stainless-steel surface was performed.
Solutions of water containing 30% (w/w) and 60% (w/w) of
potassium acetate and sodium iodide were used in the
experiments. Surface temperatures used in the
experiments ranged from 50 deg C to 100 deg C. The
average evaporation rates for the potassium acetate and
sodium iodide solutions were found to be lower than that
of pure water at a given surface temperature. A simple
evaporation model was developed to interpret the
