Abstract

Knocking down of fog system: new theoretical technique and experimental results F. Patania, A. Gagliano & F. Nocera Applied Physics Institute - Engineering Faculty of Catania University, Catania, Italy Abstract Fog can be mainly considered as a biphasic mixture of very small water drops and steam in standing balance with atmospheric air placed at a certain distance from the surface of the ground. The specific weight of fog is surly function of the amount of steam contained in the mixture that is, from time to time, function both of atmospheric temperature and pressure. It is possible to upset the standing balance between the mixture and surrounding atmospheric air in such a way to cause descending motions of fog towards the ground surface by increasing specific weight of the biphasic mixture, that is by increasing the density of fog. In research hypothesis, such increasing of mixture is achieved by sprinkling very cold particles of liquid Nitrogen into the fog such as the particles o
