This Small Business Innovation Research Phase I project focuses on developing a novel thermographic phosphor thermometry technique, combined with a thermal barrier coating (TBC) material, for monitoring gas turbine surface temperature and TBC condition (i.e., to monitor the coating for spallation and deterioration). Design of efficient and low-emission power generation gas turbines requires detailed knowledge of the temperatures, heat fluxes and flow regimes experienced by hot-gas path (HGP) components under realistic operating conditions. Hence, there is an urgent need for innovative and non-intrusive experimental techniques suitable for accurate measurement of surface temperatures in excess of 2500 K for HGP components in high-temperature regions of the gas turbine, where conventional techniques cannot be applied. In this project, a unique upconversion phosphor thermometry technology will be developed which will overcome the issues confronting widely-used down-conversion thermometry techniques. The proposed temperature sensing mechanism is independent of variations in the excitation power and environmental conditions, and hence is especially suitable for hazardous gas turbine applications. The broader impact/commercial potential of this project will be significant, because gas turbines are used to power aircraft, trains, ships, generators, and ground vehicles. Almost all manufacturers in the aerospace, transportation, and energy generation fields would benefit from the technology developed in this project. If successful, this Phase I project will directly result in an enabling technique for non-intrusive monitoring of temperature and surface conditions of materials experiencing extremely high-temperature environments. The data gathered by such a technique will also add to the scientific understanding of high-temperature combustion and fluid flow processes.

这个小型企业创新研究第一阶段项目的重点是开发一种新型的热成像磷光体测温技术，结合热障涂层（TBC）材料，用于监测燃气涡轮机表面温度和TBC条件（即，以监控涂层的飞溅和劣化）。设计高效低排放的发电燃气轮机需要详细了解实际运行条件下热气路径（HGP）部件所经历的温度、热通量和流态。因此，迫切需要创新的和非侵入性的实验技术，其适合于精确测量燃气涡轮机的高温区域中的HGP部件的超过2500 K的表面温度，其中常规技术不能应用。 在本计画中，将开发一种独特的上转换萤光测温技术，以克服广泛使用的下转换测温技术所面临的问题。 所提出的温度感测机构独立于激励功率和环境条件的变化，因此特别适合于危险气体涡轮机应用。该项目的更广泛的影响/商业潜力将是显著的，因为燃气轮机用于为飞机，火车，船舶，发电机和地面车辆提供动力。 几乎所有航空航天、运输和能源领域的制造商都将从该项目开发的技术中受益。 如果成功的话，这个第一阶段项目将直接导致一种非侵入式监测经历极高温度环境的材料的温度和表面状况的技术。 通过这种技术收集的数据也将增加对高温燃烧和流体流动过程的科学理解。
