Gas-enriched slippery surfaces

本项目将采用新颖的实验和模拟方法来研究液-液界面的气体富集及其对界面滑移的影响。该项目的成果将是更深入地了解油水界面，捕捉界面气层的存在，具有优异减阻和减污性能的光滑表面，以及在流动中控制纳米气泡的形成。这种新型表面在提高微流体和多相流的能量效率方面具有潜在的应用前景。在减少排放、燃料成本和与海上货物运输有关的污染以及从岩石中开采石油方面，预期会有好处。

This project will exploit novel experimental and simulations approaches to investigate gas enrichment at liquid-liquid interfaces, and its effect on interfacial slip. The outcomes of the project will be a deeper understanding of oil-water interfaces capturing the presence of interfacial gas layers, slippery surfaces with superior drag reducing and fouling reducing properties, and control over nanobubble formation under flow. The new surfaces will have potential application in improving the energy efficiency of microfluidic and multiphase flow. Benefits are expected in terms of reduced emissions, fuel cost and pollution related to transport of goods by sea, and extraction of oil from rocks.
