Viscosity modeling of some oxygenated fuels. do not need to formally request permission to reproduce material contained in this surfactants like detergent), each solution exhibits differing surface tension properties. © Patent search, search for pacenow for inventions - russianpatents.com 2012-2019, The invention relates to physics and chemistry of surface phenomena and can be used to study the basic interactions in the electrical double layer, The invention relates to the field of study of the properties of porous materials, in particular to the definition of the parameter wettability of the surface of the pore space of porous materials, and can be used in various industries for controlling the wettability of a solid surface natural and man-made porous media (the reservoir rocks, membranes, catalysts, powder materials, etc.,), including in the oil industry in the calculation of reserves of oil and gas, design of technological schemes of development of oil fields, The invention relates to methods of physico-chemical analysis, in particular to the determination of interfacial tension in heterogeneous systems liquid-liquid, The invention relates to the field of measurement technology, in particular, to a contactless hydrodynamic methods and devices controlling the surface tension of liquid substances and can find application in various industries, The invention relates to measuring technique and can be used in various fields of science and technology to determine some physical and mechanical characteristics of the surface layer of the liquid - speed, coefficient of surface tension, viscosity, The invention relates to a method of increasing the wettability of porous bodies of fluid and to a device for implementing this method, A device for determining the surface tension of liquids, The method for determining the wettability of porous materials, The method for determining the interfacial tension, Method of measuring surface tension of liquid media and device for its implementation, A method of measuring the surface tension coefficient of the glass, The method of determining the characteristics of the surface layer of the liquid, The method of control of physical and mechanical properties of liquid on her hesitation, The method of increasing the wettability of porous bodies and device for its implementation, Method of measurement of surface tension coefficient and static and dynamic wetting angles, Method of measuring concentration of surface-active substance, Lipid structure-phase conversions in aqueous solutions, Method for making film evaporator-oscillators, Device for measuring surface tension of solid metals, Method of determining interfacial tension at liquid-solid interface, Method of measuring surface tension of metals in solid phase, Definition of specific surface energy of ores, Method for determination of surface tension and density of liquid, Liquid surface tension and flotation agent activity tester. As the EGR rate is increased from 0% to 20%, the 10–90% MFB combustion duration is prolonged by 25.5–38.9% for alcohol/gasoline blends, and 64.1% for gasoline. Lipid components of animal, plant cells and surfactants of lipid origin are used as lipids, and water-soluble substances of inorganic, organic or biological origin are used as additives. Thus, the surface tension formula is: Surface tension = (surface force)/ (length force acts) γ = F /d. Go to our The results indicate that both the addition of EGR and alcohol show evident charge, Access scientific knowledge from anywhere. The characteristic time required to attain equilibrium surface tension is around 2 s. The droplets' size and size uniformity are two of the more important properties wherein smaller droplets will evaporate mix and burn faster than larger ones.
