Abstract
A study of droplet evaporation in three heating surfaces was conducted. Ethanol, n-heptane, and iso-octane were used as test fluids while heated surfaces tested were copper, aluminum, and stainless steel. The motivation to perform this work consists of a better understanding of how the evaporation process occurs in different surface materials. The test fluids were released onto the heated surfaces through individual drops, and the evaporation process was filmed by a digital camera. The observations were used to construct curves relating droplet lifetime with the wall temperature, and, determine the effects of the heating surface material at the Nukiyama and Leidenfrost Point. The experimental results were compared with the data found in the literature.
