The contact angle (θ) and contact radius (R) of ethanol-water mixture drop are recorded with time, considering the impacts of presence of ethanol. With excess ethanol, the drop evaporation is principally controlled by a phase in which both the contact angle and contact radius are falling. A diffusional model assuming linear relation between contact radius and time is proposed as θ = eR3 + cR1, where e and c denote fitting coefficients. This model correlates with the experimental data. | Source Title: | Drying Technology | URI: | http://scholarbank.nus.edu.sg/handle/10635/85167 | ISSN: | 07373937 | DOI: | 10.1080/07373930802046526 |
