- Abstract
- 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 experimental results.
