DISSEMINATION AND AEROSOL BEHAVIOR OF HYDROPHOBIC POWDERS
Abstract
A detailed research plan was established after review and evaluation of current data for simple chemical compounds at high pressure and high temperatures. Apparatus has been designed and is being constructed to recover particles produced by a shock and to minimize the probability of reagglomeration or further collisions. It is hoped that the apparatus can permit a permanent record of the particle distribution if this should be desirable. Theoretical considerations indicate that giving aerosol particles a net unipolar charge will increase the rate at which an aerosol cloud issuing from an apparatus will expand for reasonable aerosol concentration and charge levels. The prime uncertainty rests with the difficulty of achieving the desired charge levels. A laboratory nozzle has been designed and fabricated to permit direct assessment of this concept, using corona for charging. The project on the dissemination of hydrophobic powders has been divided into two tasks. Task 1 is a study of the behavior of solids subjected to shock loading. Task 2 is an investigation to determine whether electrically charged particles of CS agent can be used to improve the effectiveness of the dissemination process.
