Wishing to share in their experience in the use of seeding particles in laser-Doppler anemometry, some pertinent characteristics of the seeding particles generated with a mixture of water and a commercially available fog-fluid are presented. The aerosols thus generated are non-toxic, non-corrosive, non-abrasive and their lightscattering properties as well as robustness makes them well suited for measurements in air flows for velocities below 100 m/s in moderately to strongly sheared layers for moderate streamline curvatures.
