ABSTRACT:
The invention is concerned with particles consisting of a compound of an active material and foamed plastic, the mean density of the particles being adjustable to the special value of a foregiven fluid such that they can float in the fluid. Particles of this kind can be used (as "tracer" particles) for disturbance-free visualization of fluid flows and for suspending active materials of higher density than that of the fluid homogeneously in the fluid volume.
Concerning the first usage, the flow pattern of a flowing aqueous fluid is visualized by spacedly suspending in the fluid approximately spherical particles of a foamed plastic labeled with zinc sulfide phosphor and having a diameter smaller than 0.5 millimeters and by exciting the phosphor with pulses from a UV laser. Successive frames taken by an electronic camera from an electronically intensified image of the liquid permit the direction and velocity of particle movement to be monitored as a measure of the flow pattern of the fluid which is not affected by the presence of the particles.
