Abstract : The report describes the mechanics of rebound of drops, using a new method of high-speed photography. A list of the factors influencing the rebound of these drops and a qualitative explanation of the phenomenon and the energy relations involved in the rebound are given. It is concluded that: (1) fine aerosol drops, impacting on a solid surface, rebound from that surface under certain conditions; (2) in the calculation of impaction efficiency, all particles that impact on a surface are assumed to adhere to it. The latter assumption can give erroneous results under the conditions causing rebound. Under such conditions, the results of these calculations may be corrected by factors obtained experimentally.
