纳米流体是纳米级颗粒的悬浮液，它可以显著改变基础流体的化学、物理和热学性质。由于纳米颗粒浓度低，纳米流体可以在钻井液和润滑剂技术中有多种有用的应用。支持公司设计和制造具有成本效益和多功能的纳米颗粒，目前用于石油和天然气钻井液，以减少钻井泥浆损失和流体摩擦。最近的研究表明，使用纳米流体可以提高涉及加热/冷却流体的过程的传热性能。为了增加纳米流体的功能，该计划解决了纳米流体的传热问题和应用。一些参数，如体积分数，形状，尺寸和流体性质可以影响热传递增强。因此，我们将通过实验测量纳米流体的润湿、流变和热学性质，以了解这些参数的相互作用。预期的结果将导致具有增强传热性能的纳米流体的优化设计，这将有利于高性能和低成本的热交换器和加热流体。

Nanofluids are suspensions of nano-sized particles, which can change the chemical, physical, and thermalproperties of base fluids significantly. With small concentrations of nanoparticles, nanofluids can have severaluseful applications for drilling fluids and lubricant technologies. The supporting company designs andmanufactures cost-effective and multi-functional nanoparticles, which currently are used for oil and gas drillingfluids to reduce both drilling mud losses and fluid friction. Recent studies have shown that heat transferperformance of processes involving heating/cooling fluids can be enhanced by using nanofluids instead. Toincrease the functionality of the nanofluids produced, this program addresses the heat transfer problems andapplications of nanofluids. Several parameters such as volume fraction, shape, dimensions, and fluid propertiescan affect heat transport enhancement. We will thus experimentally measure wetting, rheological, and thermalproperties of the nanofluids to understand the interplay of these parameters. The expected results will lead tooptimal designs of nanofluids with enhanced heat transport properties, which can be beneficial forhigh-performance and cost-effective heat exchangers and heating fluids.
