Candles, smoke

If the light-scattering objects originally present in the airflow are unsuitable for LDA measurements due to insufficient concentration or incorrect estimated flow-tracking capability, the air must be seeded with oil smoke, tobacco smoke, or titanium dioxide tracer particles or droplets. A simple smoke candle is generally suitable for seeding, even if the enclosure is large and the air path is not closed as in several cases of industrial ventilation.
