Dye flow visualization
WebMar 5, 2024 · The visualization of flow behavior will be performed by slowly and steadily injecting dye into a pipe. The state of the flow (laminar, transitional, and turbulent) will be visually determined and compared with the results from the calculation of the Reynolds number. 5. Equipment WebDyes used for flow visualization should fulfill several requirements: Besides some general properties such as being nontoxic, noncorrosive, etc., desired properties are neutral buoyancy, high stability against mixing, and good visibility. Popular dyes for flow experiments in water are food coloring and ink.
