DESCRIPTION (provided by applicant): The long term goal of this research is to develop and commercialize an Aerodynamic Vectoring Particle Sorter (AVPS) for use as the next generation air sample concentrator for the primary purpose of environmental hazard monitoring. To accomplish this goal, the specific aim of this Phase 1 STTR project is to evaluate the technical and commercial feasibility of applying aerodynamic vectoring to particle sorting/concentrating in air. The overall research plan consists of 3 major activities: 1) a Computational Fluid Dynamics (CFD) study conducted to optimize aerodynamic flow vectoring parameters in air, 2) a set of experimental measurements, using state-of-the-art particle image tracking techniques, performed to verify CFD results and physically demonstrate the capabilities of AVPS, and 3) a comprehensive market study, focused at gathering capability and requirement data on currently available air sample concentrators and conducted to provide a standard against which the technical and commercial feasibility of an AVPS device can be assessed. The key innovation of AVPS technology is the ability to sort/concentrate a wide range of particle sizes using a single device without impact or contact of device surfaces. An AVPS device will present a faster, more reliable, more economical and less obtrusive means of sorting/concentrating air samples than is currently available. Using AVPS, the potential exists for smaller, more efficient sorting devices that operate over a wide flow rate range. In addition to environmental hazard monitoring, it is anticipated that AVPS will find application in the production of nanomaterials and carbon fibers, and in cell sorting/removal processes, where non-contact sorting methods are extremely advantageous. Aerodynamic Vectoring Particle Sorter (AVPS) technology stands to mark a substantial improvement in particle sorter design and capabilities. Using the AVPS method, faster, smaller, more reliable, more economical, and more flexible airborne sample sorting and concentration devices are possible. This research will directly benefit public health through the development and commercialization of a product that will significantly improve existing capabilities to monitor and detect of airborne environmental hazards.

描述（由申请人提供）：本研究的长期目标是开发空气动力矢量粒子分选器（AVPS）并将其商业化，用作下一代空气样本浓缩器，主要目的是环境危害监测。为了实现这一目标，第一阶段 STTR 项目的具体目标是评估将空气动力矢量应用于空气中颗粒分选/浓缩的技术和商业可行性。总体研究计划包括 3 个主要活动：1) 计算流体动力学 (CFD) 研究，以优化空气中的空气动力流矢量参数，2) 使用最先进的粒子图像跟踪技术进行一组实验测量，旨在验证 CFD 结果并以物理方式展示 AVPS 的功能，以及 3) 全面的市场研究，重点收集当前可用空气样本浓缩器的能力和需求数据，并提供一个标准，以衡量技术和商业可行性可以评估 AVPS 设备的性能。 AVPS 技术的关键创新是能够使用单个设备对各种粒径进行分类/浓缩，而不会影响或接触设备表面。 AVPS 设备将提供比目前可用的更快、更可靠、更经济且不那么引人注目的空气样本分类/浓缩方法。使用 AVPS，有可能实现更小、更高效、可在较宽流速范围内运行的分选设备。除了环境危害监测之外，预计 AVPS 将在纳米材料和碳纤维的生产以及细胞分选/去除过程中得到应用，其中非接触式分选方法极为有利。空气动力矢量粒子分选机 (AVPS) 技术标志着粒子分选机设计和功能的重大改进。使用 AVPS 方法，更快、更小、更可靠、更经济且更灵活的机载样品分选和浓缩装置成为可能。这项研究将通过产品的开发和商业化直接造福公众健康，该产品将显着提高现有的监测和检测空气环境危害的能力。
