Overview
Flow visualization is the art of making flow patterns visible. Most fluids (air, water, etc.) are transparent, thus their flow patterns are invisible to us without some special methods to make them visible.
Historically, such methods included experimental methods, like say spilling ink into water. With the importance of computer models in all kinds of engineering growing and huge amounts of data collected from simulating flow processes (e.g. the distribution of air-conditioned air in a new car), purely computational methods have been developed.
