|Title:||Evaporation of ethanol-water mixture drop on horizontal substrate|
|Citation:||Wang, Z., Peng, X.-F., Mujumdar, A.S., Su, A., Lee, D.-J. (2008-06). Evaporation of ethanol-water mixture drop on horizontal substrate. Drying Technology 26 (6) : 806-810. ScholarBank@NUS Repository. https://doi.org/10.1080/07373930802046526|
|Abstract:||This study investigates the evaporation of sessile drop comprising ethanol and water mixture on horizontal poly methyl methacrylate surface. 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.|
