Investigation of drop geometry at free-falling process depending on volume of dozing

Abstract

Abstract. Present work performs experimental investigation of the changes in the geometric shape of the drop in terms of its free-falling, depending on the conditions of drop formation on dispenser. It was found that volume and velocity of drop formation on dispenser are the factors affecting the geometric shape of the drop in terms of its free-falling.

Using A High-Temperature Flue Gases in the Technology of Combustion Neutralization of Wastewater

“…However for projection and practical use of this technology of energy saving requires carrying out theoretical and experimental researches for determination of the main features and regularities of evaporation of water and burning out of impurity of technological wastewater at dispersion in the environment of hightemperature combustion gases. At that time there are published results of researches of major mechanisms and regularities of the movement of evaporation of drop streams of liquids at contact with hot gases and the heating surfaces [9,10]. For development of technology of high-temperature wastewater treatment with using of hot combustion gases similar results of researches are necessary for drop streams of liquid with combustible contaminants.…”

Experimental study of a drop “evolution” under conditions of its free fall on a heated surface

“…It is necessary to control their spatial distribution and spreading when they impact the surface in order to prevent the merging of adjacent drops. A drop spreading over a solid surface is found to depend on the gravity forces, inertia, viscosity, friction and surface tension [7][8][9][10]. The weight of the drop affects the gravity force; liquid composition affects the viscous friction force and surface tension; mass of liquid and surface roughness on mechanical friction.…”

Forced spreading over superhydrophobic and copper surfaces

“…However there are no scientific bases [9][10][11][12] to control the wetting process. It happens due to the lack of available registration equipment of fast processes of wetting and spreading.…”
