This Small Business Innovation Research (SBIR) Phase II project is to develop a low cost educational Particle Image Velocimetry (ePIV) suite including both hardware and software for fluid science and engineering education at university undergraduate and graduate school levels. The proposed PIV is the state of the art technology in fluid flow research that enables visual and quantitative analysis of the flow field. Industrial/research level PIV system usually costs over $100,000. The high cost and safety considerations - because of the use of high power Class IV lasers - prohibit adaptation of PIV systems in the US higher education system. Current PIV systems typically use two pulse lasers with 50 mJ/pulse energy and 5 nanossecond pulse duration. This translates to a total power of 10 mega Watts if it was a continuous laser. In summary, although it is very challenging to develop a PIV system that works with only a single 15 milliwatt continuous laser and a regular CCD camera, the Phase I outcomes indicate that it is feasible. The project will create learning materials by developing software as a virtual teaching assistant for the education process, where the students can develop enhanced understanding of fluid flow by interactive experiments through a computer terminal in the classroom. Hence, the software will be an instrument that can be used in diverse educational settings because of its effectiveness as an education tool, high-tech appeal, compact size, low cost and safety.Fluid mechanics is a highly visual subject. During the teaching process one must take full advantage of this fact. ePIV gives the opportunity to achieve this to its full extent making this technology easily accessible. The educational suite will provide faculty the latest technology as a teaching tool at a very affordable price, allowing them to acquire new knowledge and skills and to revise their curricula and teaching practices. The low cost of ePIV will allow schools with very limited budgets to use and teach the state of the art technology to their students. The project envisions bringing this new technology from technical colleges to BS, MS and Ph.D. granting institutions. Due to its simplicity of operation, low cost and being highly visual, the ePIV technology can even be used at museums, science centers and similar institutions to develop exhibits in science and engineering. This tool can also be used to promote fluid mechanics and science in general even to non-science and non-engineering students.

这个小型企业创新研究（SBIR）第二阶段项目是开发一个低成本的教育粒子图像测速（ePIV）套件，包括硬件和软件，用于大学本科和研究生院水平的流体科学和工程教育。PIV是流体流动研究中的最先进技术，可以对流场进行可视化和定量分析。工业/研究级别的PIV系统通常花费超过10万美元。由于使用高功率IV类激光器，高成本和安全考虑因素禁止美国高等教育系统采用PIV系统。当前的PIV系统通常使用两个脉冲激光器，脉冲能量为50 mJ/脉冲，脉冲持续时间为5 ns。如果是连续激光器，这意味着总功率为10兆瓦。总之，尽管开发仅使用单个15毫瓦连续激光器和常规CCD相机的PIV系统非常具有挑战性，但第一阶段的结果表明它是可行的。该项目将通过开发软件作为教育过程的虚拟教学助手来制作学习材料，学生可以通过教室中的计算机终端进行互动实验，加深对流体流动的理解。因此，该软件将是一种工具，可以在不同的教育环境中使用，因为它的有效性作为一种教育工具，高科技的吸引力，紧凑的尺寸，低成本和安全。流体力学是一个高度可视化的主题。在教学过程中，必须充分利用这一点。ePIV提供了充分实现这一目标的机会，使这项技术易于使用。教育套件将以非常实惠的价格为教师提供最新的技术作为教学工具，使他们能够获得新的知识和技能，并修改他们的课程和教学实践。ePIV的低成本将使预算非常有限的学校能够使用和向学生教授最先进的技术。该项目设想将这项新技术从技术学院带到BS，MS和博士。授予机构。由于其操作简单、成本低和高度可视化，ePIV技术甚至可以用于博物馆、科学中心和类似机构，以开发科学和工程方面的展品。这个工具也可以用来促进流体力学和科学一般甚至非科学和非工程专业的学生。
