Smoke: a Study of Aerial Disperse Systems

Abstract

IN this book the authors give a connected account of the large body of work on disperse systems in air which they have for some years been carrying out at Leeds, together with the relevant researches of other investigators. The subject is one of considerable theoretical and practical interest. On the theoretical side, the contrast in properties between a substance dispersed in a liquid medium and one dispersed in a gas throws light on the mechanism of general processes in sols, such as that of coagulation on the practical side, the coagulation of smokes assumes particular importance in the industrial precipitation of fumes and in the consideration of urban fogs while as an example of the bearing of the subject on the world of atomic physics, we may quote the experiments of Ehrenhaft on the sub-electron, the fallacious conclusions of which our authors trace to a neglect of the processes of coagulation common to all smokes.
