AB The methods of flow visualization serve for visualizing the motion of fluids that are normally transparent and invisible to the naked eye. Following a postulation of Hermann von Helmholtz, visual perception of the processes under study supports the understanding of the seen or recorded phenomena, here: developing a physical model of the flow processes. This postulation requires a link between the eye and brain where a sufficient knowledge from the past must be stored in order to interpret the visible information. Among all possible sensations, seeing is the most significant source for "constructing a picture of the world" (Ernst Mach). Therefore, quantitative data on physical processes, obtained by measurements or calculations, are most frequently displayed in a visible form in order to facilitate the understanding of their meaning. A flow picture includes an abundance of quantitative data; a number of fundamental flow phenomena unknown before have been discovered by appropriate visualization, e.g., the existence of a supersonic flow, or the formation of coherent structures in turbulent flow.
