Droplet evaporation on heated hydrophobic and superhydrophobic surfaces.
The evaporation characteristics of sessile water droplets on smooth hydrophobic and structured superhydrophobic heated surfaces are experimentally investigated. Droplets placed on the hierarchical superhydrophobic surface subtend a very high contact angle (∼160°) and demonstrate low roll-off angle (∼1°), while the hydrophobic substrate supports corresponding values of 120° and ∼10°. The substra...
متن کاملMulticomponent Droplet Evaporation on Chemical Micro-Patterned Surfaces
The evaporation and dynamics of a multicomponent droplet on a heated chemical patterned surface were presented. Comparing to the evaporation process of a multicomponent droplet on a homogenous surface, it is found that the chemical patterned surface can not only enhance evaporation by elongating the contact line, but also change the evaporation process from three regimes for the homogenous surf...
متن کاملSteady State Analysis of Nanofuel Droplet Evaporation
The potential for nanofuels as one of the clean sources of energy on account of its enhanced combustion performance coupled with low emissions has been established. Considering the importance of the fuel evaporation phase in the entire combustion process, this work presents an attempt at applying the steady state analysis equations to nanofuel experimental data obtained from the li...
متن کاملDroplet evaporation of pure water and protein solution on nanostructured superhydrophobic surfaces of varying heights.
Evaporation of liquids on substrates is important for many applications including lab-on-a-chip, especially when they are in droplets. Unlike on planar substrates, droplet evaporation on micropatterned substrates has been studied only recently and none so far on nanopatterns. Driven by the applicability of nanostructured surfaces to biomaterials and tissue engineering, we report on the evaporat...
متن کاملExperimental and theoretical investigations of evaporation of sessile water droplet on hydrophobic surfaces.
Experiments of sessile water droplet evaporation on both polydimethylsiloxane (PDMS) and Teflon surfaces were conducted. All experiments begin with constant contact area mode (the initial contact angle is greater than 90°), switch to constant contact angle mode and end with mixed mode. Based on the assumptions of spherical droplet and uniform concentration gradient, theoretical analyses for bot...
