A selection of drift parameters (density, dimension) of flare particles for display and optical diagnostics of vortex flows is considered. An expression for use in finding the dynamic relaxation time of these particles, which track the movement of a gas in vortices of different intensities, is obtained. An example of a selection of characteristics of the particles for display of a spout and cascade of a laboratory-simulated air vortex is presented.
