This project employs a sophisticated research technique, Particle Image Velocimetry (PIV), to enhance undergraduate teaching. PIV is more commonly used as a research tool to study fluid mechanics and convective heat transfer. The techniques for the use of this tool to make full field, instantaneous, quantitative velocity measurements, after those of researchers at the University of Minnesota, Florida State University, and Lehigh University, will be adapted to undergraduate courses and laboratories in the thermal sciences. These adaptations of courses and laboratories support Union College's philosophy of three stages of investigative learning designed to prepare students for collaborative research with faculty by the senior year. This three stage program includes introductory courses emphasizing hands-on activities as well as the fundamentals, mid-level courses focusing on research-like experiences through open-ended projects, and senior research experiences designed to sharpen inquiry skills. The improvement of student ability to perform fluid mechanics and heat transfer design, the development of student intuition about the effects of fluid mechanics on heat transfer, and the potential to excite students about the thermal fluid sciences are expected project outcomes. The PIV system will be integrated throughout the mechanical engineering curriculum at Union College and will serve as a model for enhancing the instruction of the thermal sciences throughout four year undergraduate mechanical engineering curricula.

本项目采用先进的研究技术，粒子图像测速（PIV），以加强本科教学。PIV更常被用作研究流体力学和对流传热的研究工具。在明尼苏达大学、佛罗里达州立大学和里海大学的研究人员之后，使用该工具进行全领域、瞬时、定量速度测量的技术将适用于热科学的本科课程和实验室。这些课程和实验室的调整支持了联合学院研究性学习的三个阶段的理念，旨在为学生在大四之前与教师合作研究做好准备。该课程分为三个阶段，包括强调实践活动和基础知识的入门课程，通过开放式项目关注研究体验的中级课程，以及旨在提高探究技能的高级研究体验。提高学生进行流体力学和传热设计的能力，培养学生对流体力学对传热影响的直觉，并有可能激发学生对热流体科学的兴趣，是预期的项目成果。PIV系统将被整合到联合学院的整个机械工程课程中，并将作为一个模型，在整个四年制本科机械工程课程中加强热科学的教学。
