This Small Business Innovation Research Phase I project focuses on the development of 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 cost of energy, use of consumables, fouling, and limited efficiency in separation of micron-sized particles. The proposed large volume flow rate acoustophoretic separation technology does not generate waste, does not use consumables, operates at a low cost of energy, 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 force and buoyancy. The action of the acoustic forces on the trapped particles results in concentration, agglomeration and/or coalescence of particles and droplets. Heavier than water particles are separated through enhanced gravitational settling, and lighter particles through enhanced buoyancy. This project combines experiment and computer modeling to probe the interaction between piezo-electric transducers and the acoustic field to maximize the acoustic trapping potential and to provide results to create scalable systems and economic models of capital and operational expense of the technology. 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 of acoustic radiation force in ultrasonic standing waves. A full three-dimensional accounting of the acoustic radiation force in realistic geometries will be done. 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. FD 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.

这个小型企业创新研究第一阶段项目的重点是开发一种经济、高效、可持续、环保的新型超声声光分离技术。目前的技术，如水力旋流器和膜过滤，都存在一些问题，如能源成本高、耗材使用、污染和微米级颗粒分离效率有限。所提出的大体积流速声波分离技术不产生废物，不使用消耗品，以低能源成本运行，并提供微米级颗粒的高效分离。超声波驻波用于捕获流体中的二次相颗粒，当施加在颗粒上的声辐射力大于流体阻力和浮力的综合作用。声力对被困颗粒的作用导致颗粒和液滴的集中、聚集和/或聚并。比水重的粒子通过增强重力沉降分离，而较轻的粒子通过增强浮力分离。该项目将实验和计算机建模相结合，探索压电换能器与声场之间的相互作用，以最大限度地提高声捕获潜力，并提供结果，以创建可扩展的系统，以及该技术的资本和运营费用的经济模型。该项目更广泛的影响/商业潜力在于，新型声波分离技术为多组分相混合物的能量分离提供了更便宜和更低的成本。它可以替代传统的分离技术，如水力旋流器和其他方法。社会影响是分离技术的发展，这种分离技术是可持续的，对环境无害的，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，为提高采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。本项目增加了超声驻波声辐射力的科学技术。一个完整的三维计算声辐射力在现实几何将做。我们将通过在同行评议的期刊和会议上发表我们的研究结果来传播这项工作。该项目为工科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。FD sonic有着悠久的历史，并致力于通过提供实习机会和为高年级学生提供顶点设计项目的监督，让本科生参与到他们的技术开发中来。
