Summary:

Throughout history, flow visualization has been an important tool in fluid dynamics research. It has been used extensively in the fields of engineering, physics, medical science, meteorology, oceanography and sport aerodynamics, to name just a few. The importance of flow visualization led Professor F N M Brown (1971) of the University of Notre-Dame to comment, "... A man is not a dog to smell out each individual track, he is a man to see, and seeing, to analyze..." This statement encapsulates the importance of first visualizing the flow before proceeding with detailed measurement and mathematical
