Incorporating Research into a First-Year Fluid Mechanics Class

Abstract

Through simple flow visualization experiments, it is possible to introduce students to research in fluid mechanics during their first fluid mechanics course. Our visual sense is so powerful that in an instant we can often grasp both the big picture and the detail. To quote Richard Feynman, considered to be one of the top scientists of the 20th century, ‘fundamental questions can be easily answered just by looking at the thing‘. One should know, however, precisely how to look, analyze and investigate visually. Interesting small-scale fluid motion may be observed and photographed to reveal fundamental processes in an inexpensive and team-building manner that builds confidence, gives students skills for lifelong learning, and prepares them for graduate research. This paper presents our students' experience.
