Title:
IDENTIFYING THE MECHANISMS OF ENHANCED WATER FLOW THROUGH CARBON NANOTUBES

Authors:
Thomas, JA; McGaughey, AJH

Author Full Names:
Thomas, J. A.; McGaughey, A. J. H.

Abstract:
Pressure-driven water flow through carbon nanotubes (CNTs) with diameters ranging from 1.66 nm to 4.99 nm is examined using molecular dynamics simulation. The flow rate enhancement, defined as the ratio of the observed flow rate to that predicted from the no-slip Hagen-Poiseuille relation, is calculated for each CNT The enhancement decreases with increasing CNT diameter and ranges from 433 to 47. By calculating the variation of water viscosity and slip length as a function of CNT diameter, it is found that the results can be fully explained in the context of continuum fluid mechanics. The enhancements are lower than previously reported experimental results, which range from 560 to 100000, suggesting a miscalculation of the available flow area and/or the presence of an uncontrolled external driving force (such as an electricfield) in the experiments.

Title:
EFFECT OF GEOMETRIC PARAMETERS OF SUPERHYDROPHOBIC SURFACE ON LIQUID SLIP

Abstract:
In this paper, we experimentally study how geometric parameters of textured hydrophobic surfaces affect a liquid slip, empowered by a custom-tuned microfabrication procedure that produces regular micro-patterns of posts and grates on an entire 4" wafer with a good size uniformity and no defect. A pitch of the patterns and a gas fraction of the structured surface are independently controlled, and the slip length over each type of patterns is measured using a rheometer system. On both grates and posts, the slip length increases linearly with a pitch but exponentially with a gas fraction. The trend of exponential increase by gas fraction appears more pronounced on posts than on grates. The defect-free surfaces allow the flows to maintain a de-wetted (Cassie) state at much higher pitches and gas fractions than previously possible, permitting flows with the maximum slip effect.
