Collaborative Research: Phase Two Development of a Self-Contained Underwater Velocimetry Apparatus

为解决这一问题，PIS已经建立了一个原位数字粒子图像测速(DPIV)系统的原型--自给式水下测速仪器(SCUVA)，并进行了初步测试，以确定其可行性。PIS要求资金开发SCUVA系统的第二阶段版本，该系统将包括用于现场潜水员评估的实时数据处理和显示、使用粒子跟踪速度计(PTV)的三维流动测量、运动稳定性和改进的人体工程学。第二阶段的SCUVA将进行实地测试，并编写其使用的指导材料，以促进与其他感兴趣的调查人员交流这项技术。更广泛的影响建议的仪器将可供其他研究人员用于他们的项目。拟议的手册将有助于其他研究人员使用和测试SCUVA的能力。此外，还计划让本科生和研究生参与仪器的建造和测试。科斯特罗和科林在将学生纳入他们的研究方面有着坚实的记录。过去，他们的本科生会在国家科学会议上展示他们的工作。这将是这些学生在跨学科研究和仪器开发方面的一个很好的学习机会。

The PIs have built a prototype in situ digital particle image velocimetry (DPIV) system, the Self- Contained Underwater Velocimetry Apparatus (SCUVA), to address this problem and have performed preliminary tests to determine its feasibility. The PIs request funds to develop the second phase version of the SCUVA system that will incorporate real time data processing and display for in situ diver evaluation, three dimensional flow measurement using particle tracking velocimetry (PTV), motion stabilization and improved ergonomics. The second phase SCUVA will be field tested and tutorial materials for its use developed to facilitate exchange of this technology with other interested investigators. Broader ImpactsThe proposed instrumentation will be available to other researchers for their projects. A proposed manual will aid in the ability of other researchers to use and test the SCUVA. In addition, there are plans to include undergraduate and graduate students in the building and testing of the apparatus. Costello and Colin have a solid track record in including students in their research. In the past, their undergraduate students have presented their work at national scientific meetings. This will be a great learning opportunity in interdisciplinary research and instrumentation development for these students.
