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.

该项目将利用新的实验和模拟方法来研究液-液界面处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，捕获界面气体层的存在，具有上级减阻和减垢特性的光滑表面，以及对流动下纳米气泡形成的控制。这些新的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。预计将在减少排放、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产生惠益。
