So far visualization of the flow, [1] has involved heating the wire with paraffin oil placed across the horizontal axis of the nozzle. The point of the idea of a continuous visualization is to change a hot wire for a thin pipe with holes for steam of paraffin. The digital camcorder was used. For improvement of visibility, optical arrangement was used. The air stream is illuminated by a bundle of light with a defined thickness. The quantity of paraffin steam depends on tension of alternating current.
