In Situ Formation of Stable Foam in Sea Water to Cause Salty Wind Damage (II)

Wind Transport of Stable Foam Massesby

Abstract

In the winter monsoon season enormous masses of stable foam are produced along the shore of the Japan Sea in the Tohoku District. Wind action may then disperse the accumulated foam in fragments and carry them inland, and much damage has been caused to the electrical facilities, and to trees and farm products.
In this paper wind transport phenomena and related characteristics of stable foam of sea water were treated using data obtained in situ and in the laboratory. Thus, we have found that the change in the density of stable foam is primarily due to drainage of sea water from the bubble membranes, and that this is given by the formula.
d=C₁e^-k1+C₂ where d, t, C₁, C₂, and k are respectively density, time and characteristics of the foam.
