This Small Business Innovation Research Phase I project will establish a method to quantitatively predict the level of micromixing and mass transport in single-phase and multiphase fluid systems that are generated by a novel low-frequency acoustic technology. The primary Phase I objective is to demonstrate the feasibility for development of a theoretical understanding of the governing mechanisms for the transformation of high-intensity, low-frequency, acoustic energy radiation into useful work for mixing and mass transport applications in multi-phase fluids. A secondary, but essential, objective will be to develop the transfer functions coupling the acoustic transducer to the radiated acoustic energy in the fluid. The models will be accompanied by experiment methods that will correlate classical micromixing amd mass transport techniques with acoustic field experiment data. The proposed work will result in establishing a fundamental understanding of the governing mechanisms for acoustically-driven, single-phase and multiphase fluid processes, as well as fluid-particle interactions. The analytical models are essential for exploitation of the industrial market by innovative low-frequency acoustic mixing methods that are emerging. Mixing is the most common operation encountered in the Chemical Processing Industries. In North America alone, the conventional industrial mixer market is between $200 million and $250 million annually. Other industries reliant upon mixing and mass transport include food, petroleum, mining, pharmaceutical, pulp and paper, water treatment and municipal waste water treatment.

该小型企业创新研究第一阶段项目将建立一种方法来定量预测由新型低频声学技术产生的单相和多相流体系统中的微混合和质量传递水平。 第一阶段的主要目标是证明对高强度、低频声能辐射转化为多相流体混合和质量传输应用的有用功的控制机制进行理论理解的可行性。 次要但重要的目标是开发将声换能器耦合到流体中的辐射声能的传递函数。 该模型将附带将经典微混合和质量传输技术与声场实验数据相关联的实验方法。 拟议的工作将有助于建立对声驱动、单相和多相流体过程以及流体-颗粒相互作用的控制机制的基本理解。 分析模型对于通过新兴的创新低频声学混合方法开拓工业市场至关重要。 混合是化学加工行业中最常见的操作。 仅在北美，传统工业搅拌机市场每年就在 2 亿至 2.5 亿美元之间。 其他依赖混合和集体运输的行业包括食品、石油、采矿、制药、纸浆和造纸、水处理和城市废水处理。
