This Small Business Innovation Research (SBIR) Phase II project focuses on a novel ultrasonic acoustophoretic separation technology that is economic, efficient, sustainable, and environmentally benign. Current technologies, e.g., hydrocyclones, and membrane filtration, suffer from problems, such as high energy costs, use of consumables, fouling, and limited efficiency in separation of micron-sized particles. The proposed technology does not generate waste, does not use consumables, operates at a low energy cost, and provides efficient separation for micron-size particles. Ultrasonic standing waves are used to trap secondary phase particles in a fluid stream, when the acoustic radiation force exerted on the particles is stronger than the combined effect of fluid drag and buoyancy. The action of the acoustic forces on the trapped particles results in agglomeration and/or coalescence of particles and droplets. Heavier than water particles are separated through enhanced gravitational settling, and lighter particles through enhanced buoyancy. During Phase I, successful prototypes were designed with a separation efficiency of more than 90% of a 1000 ppm emulsion at flow rates of 2500 Liters per minute. Phase II focuses on the development of a system capable of processing 4 gpm, with fully integrated customized electronics, and testing of the system on real-world emulsions.The broader impact/commercial potential of this project is that the novel acoustophoretic separation technology provides for a cheaper and lower cost of energy separation of multi- component phase mixtures. It can function as a drop-in replacement for conventional separation technology, such as hydrocyclones and other methods. The societal impact is the development of separation technologies that are sustainable and environmentally benign since they do not generate any waste or use consumables. Enhanced extraction of micron-sized oil droplets from water offer opportunities for enhanced oil recovery and oil-spill cleanup and reduce the emission of micron-sized oil droplets into the environment. This project increases the science and technology behind the use of acoustic radiation force on large volume flow rate. Full numerical models will be created to use in conjunction with experimental results. Dissemination of this work will be done by publishing our results in peer reviewed journals and conferences. This project provides several internships to undergraduate engineering students, an opportunity to learn and practice engineering, innovation, and entrepreneurship at a small start-up company. FloDesign Sonics has a strong history and commitment to integrating undergraduate students in the development of their technology through offering internships and providing supervision for senior capstone design projects.

这个小企业创新研究（SBIR）第二阶段项目的重点是一种新型的超声波声泳分离技术，是经济，高效，可持续和环境友好。 目前的技术，例如，水力旋流器和膜过滤存在诸如高能量成本、消耗品的使用、结垢和分离微米尺寸颗粒的有限效率的问题。 所提出的技术不产生废物，不使用消耗品，以低能源成本运行，并为微米级颗粒提供有效的分离。 当施加在颗粒上的声辐射力强于流体阻力和浮力的组合效应时，超声驻波用于捕获流体流中的第二相颗粒。 声力对捕获的颗粒的作用导致颗粒和液滴的聚集和/或聚结。 比水重的颗粒通过增强的重力沉降分离，较轻的颗粒通过增强的浮力分离。 在第一阶段，成功的原型设计与超过90%的1000 ppm的乳液在2500升每分钟的流速分离效率。 第二阶段的重点是开发一个能够处理4 gpm的系统，完全集成定制的电子设备，并在真实世界的乳液上测试该系统。该项目更广泛的影响/商业潜力是，新的声泳分离技术提供了一个更便宜和更低成本的多组分相混合物的能量分离。 它可以作为传统分离技术的替代品，如水力旋流器和其他方法。 社会影响是可持续和环境友好的分离技术的发展，因为它们不产生任何废物或使用消耗品。 提高从水中提取微米级油滴的能力为提高石油回收率和清理溢油提供了机会，并减少了微米级油滴向环境中的排放。本项目增加了科学技术背后的大体积流量使用声辐射力。将建立完整的数值模型，与实验结果结合使用。这项工作的传播将通过在同行评审的期刊和会议上发表我们的结果来完成。 该项目为工程专业本科生提供了几个实习机会，让他们有机会在一家小型初创公司学习和实践工程、创新和创业精神。 FloDesign Sonics有着悠久的历史，并致力于通过提供实习机会和为高级顶点设计项目提供监督，将本科生融入他们的技术开发。
