WebFlow visualization methods have been developed and used extensively to demonstrate flow patterns around cylinders, around wings, through orifice meters, about turbine blades [Anapu, et al, 2], and much more. Various techniques have been use including hydrogen bubble generation, dye injection, and more recently, the ink dot method. 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. tauranga to new plymouth flights
