A solid particle seeder for particle-based laser measurement techniques in low volume-flowrate gas streams

This article describes a device to seed solid micron-size particles into gases for particle-based laser diagnostic techniques. The particle seeder consists of a sealed vessel containing the particles, into which the gas to be seeded is introduced. Using an electric fan placed inside the vessel, a fine aerosol can be easily generated. It is demonstrated that (1) at a fixed fan speed the particle seeding density Np can be kept within the range...
