Abstract
A method of flow visualization comprises the steps of coating the surface of a component in a pigmented oil-based paint of non-gelling characteristics, applying dry dye particles, which are soluble in the oil based paint to the surface of the coating and passing a fluid flow over the component. The fluid flow causes the dye particles to translate across the coating so that regions of the particles that are in contact with the coating dissolve to leave trails on the surface of the coating which are indicative of the relative strengths of the fluid flows acting on the surfaces of the component.
