WHY MAKING USE OF FLOW VISUALIZATION?
Краткое описание
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.
