Educational Interactive Flow Visualization & Analysis System Users

"Pre and post-test data demonstrated that students, aided by ePIV as well as Flowcoach, achieved practically and statistically significant growth in their mastery of course content during the fall semesters of both years...Students' outcomes provided evidence that the ePIV/Flowcoach systems were effective in assisting students' understanding of the principles of PIV techniques and relevant fluid dynamics theories. Students' scores on lab reports showed evidence for acquisition of skill and knowledge related to the overall lab implementation goals. Students' growth between pre and post tests was substantial both for knowledge as measured and for their confidence ratings of that knowledge. Survey results demonstrated that as a result of the ePIV/Flowcoach labs, students could conduct experiments and analyze the ePIV/Flowcoach results to gain increased understanding of fluid physics."

Some of the users around the World:

Here is what some of the students said about the ePIV system (courtesy of University of Iowa):

• 'The hands on experience was very informal, especially the ePIV' … 'It helped in the understanding of the wake of an object and the turbulence that forms'
• 'Using the different features of the ePIV system was extremely interesting and allowed students to see firsthand the flow of fluids. It gave a much more visual lesson than simply reading or hearing about it' …
• '… it was nice to see how all the different settings in FLOWEX software affected the picture. It definitely gave us a good idea how liquid flows around a material' …
• 'The ePIV was easy to use and understand' … 'The lab was enjoyable and I look forward to more hands on experience'
• 'The ePIV system showed us the future of how fluids will be analyzed'
• 'Fluid flow imagery with ePIV was …, and greatly increased comprehension of Reynolds number topics'
• '… ePIV equipment allows for clear observable results to be made'
• 'This experiment was a lot of fun. I enjoyed … and the ePIV analysis. The software was easy to work with and the lab equipment was very user-friendly'
• 'The FLOWEX software interface for the ePIV system was very user friendly and easy to understand'
• '… it was interesting to actually analyze the flow in the system. It definitely gave us a better idea how liquid flows by putting everything in data form …'
• 'The ePIV system was very fascinating and I think more experiments using that device would be very advantageous'
• '… being able to visualize the physical properties at work was very beneficial'
• '… to work with ePIV flows which I feel more confident with the more I see'
• '… The ePIV system also enabled me to see the velocity magnitude contours, which as a hazy concept before this experience'
• 'The ePIV in this lab actually was of some use which is not what has accrued in the last labs. It allowed me to actually see how a fluid flows around an airfoil at different angles. Having a picture of what we were calculating allowed me to better understand what I was actually calculating. All the different plots also, made it easier to see what happening as the liquid was passed over the airfoil. Overall I found this lab to a success and gave me an overall better understanding of the fluid mechanics'
