SBIR Phase I: Nonintrusive Species Specific Velocimeter

这个小型企业创新研究（SBIR）第一阶段项目将开发一种光学仪器，该仪器可以测量火焰中不同物种的速度分布，并且可以在多个尺度上测量，精度为1%。这种新型测速仪是非侵入式和被动的，完全依靠火焰本身发出的光。该仪器将与商业燃烧化学气相沉积方面的专家共同开发，这是一种廉价生产薄膜涂层的工艺，适用于各种应用，包括电子、玻璃、防腐、超导体、催化剂、聚合物和纳米粉末。测速仪将监测火焰中的物质混合和速度，促进“智能”沉积，简化实时过程控制，提高涂层过程的可靠性。该仪器将绘制火焰的整体速度图。第一阶段将证明物种特异性、可变尺度尺寸测速的可行性。第二阶段将使用原型仪器进行原理验证演示。主要的商业应用是智能沉积，它可以实时监测火焰中特定物种的速度分布，以保持火焰的一致性并最大限度地提高沉积效率。其他潜在的应用包括基于等离子体的制造和等离子体推进器控制。

This Small Business Innovation Research (SBIR) Phase I project will develop an optical instrument that measures velocity distribution in a flame species by species---and on multiple scale sizes---with an accuracy of 1%. This novel velocimeter is nonintrusive and passive, relying completely on light emitted by the flame itself. The instrument will be developed with experts in commercial combustion chemical-vapor deposition, a process that inexpensively produces thin-film coatings for a variety of applications, including electronics, glass, anti-corrosives, superconductors, catalytics, polymers, and nanopowders. The velocimeter will monitor species mixing and velocity in the flame, facilitating "smart" deposition that can streamline real-time process control and increase the reliability of the coating process. The instrument will map the velocity of the flame as a whole. Phase 1 will prove the feasibility of species-specific, variable-scale-size velocimetry. Phase II will perform a proof-of-principle demonstration with a prototype instrument. The principal commercial application is smart deposition that monitors real-time species-specific velocity distribution in a flame to maintain flame consistency and maximize deposition efficiency. Other potential applications include plasma-based manufacturing and plasma thruster control.
