The chemical and physical investigation of germicidal aerosols: II. The aerosol centrifuge

  • S. R. Finn (a1) and E. O. Powell (a1)

Extract

The principle of the aerosol centrifuge is described, and an elementary mathematicaltreatment is given.

The relations between the behaviour of the centrifuge and its dimensions, speed and airflow have been tested experimentally on three machines. It is shown that the mathe-matical formulae given are an adequate basis for design.

Various applications are mentioned.
