Flow visualization is direct observation of the flow field,
usually accomplished in a laboratory. Several photographs in this
book (see Figs. 3.1, 9.19, and 11.4) and the majority of the accompanying videos were made with the aid of a flow visualization
technique. Do some research on flow visualization techniques,
including those for both incompressible and compressible flows.
Find examples of the use of flow visualization to solve engineering problems. Prepare a paper on your findings; be sure to include
several pictures.
