Аннотация: (English) In this publication, the author revisits the issue of three-dimensional hydraulic shape memory in emulsions obtained using a proprietary complex method and a multifunctional apparatus invented specifically for this purpose. The technology and apparatus were tested on a water-in-oil emulsion, where diesel fuel No. 2 was used as the oil phase and regular drinking water with a hardness salt concentration of up to 200 mg/L was used as the aqueous phase. During the design of the test bench, the latest trends in the application of emulsions as fuel were taken into account, including their use in modern diesel engines, diesel generators, industrial boilers, and turbines. For diesel engines and boilers, one of the most challenging aspects of the fuel injection and combustion process is fuel flow separation before the high-pressure pump. In this stage, the majority of the fuel flow is directed to the high-pressure pump (which today operates at pressures of 2000 bar and above) before being injected into the combustion chamber of a boiler or the cylinders of an engine, while a smaller portion is returned to the fuel tank. When using conventional single-component diesel fuel, this principle does not cause any issues. However, in the case of emulsified fuels, such a fuel supply method leads to instability in the emulsion, disrupting its homogeneity and uniform distribution of water and oil (diesel fuel) throughout the volume.

Аннотация: (Українська) Використання насосних агрегатів є невід’ємною складовою комунальних господарств. Вітчизняна промисловість з початку ХХ століття виробляє велику номенклатуру гідромашин усіх типів. Серед них з часом з’явився новий тип – вільновихрові насоси. У цій статті проведено порівняння насосу типу СВН з популярним насосом типу ГНОМ (грязьовий насос одноступеневий моноблоковий). Висвітлено теоретичні переваги та недоліки кожного з типів насосів на основі даних технічної документації компаній-виробників. Складено порівняльну таблицю з основними даними насосних агрегатів.

Аннотация: (English) This article provides a brief overview of key fragments of an integrated technology that determine its applicability across various technical and commercial scenarios. In all cases, the focus is on a single type of device that performs dynamic mixing and simultaneous dynamic homogenization of liquid and gaseous physical media. The article explores all potential aspects of the technology and the device that implements it. Special attention is given to dynamic reagent-free homogenization as a fundamental integrative process that enhances the accuracy of non-contact monitoring of liquid conditions in pipelines. These pipelines can be monitored using aerial imaging or unmanned aerial vehicles (UAVs). For the successful commercialization of this integrated technology, it is crucial to identify all viable implementation opportunities—specifically those where the technology is clearly in demand.

Аннотация: (English) When using gasoline-ethanol fuel blends, there is always a risk of phase separation into organic fractions and water (inherent in ethanol). The higher the ethanol content in the blend, the more significant the negative impact of phase separation into organic components and water. This paper proposes a device with no moving parts, installed in the fuel pipeline between the fuel pump and the high-pressure pump. The fuel pump outlet is connected to a splitting tee, which divides the fuel flow into two streams. These streams undergo turbulence-level homogenization within the device, and if water is present in the gasoline-ethanol mixture, it is dynamically emulsified during the homogenization process. The dynamic emulsion exiting the device then enters the engine’s high-pressure pump, where, under high-pressure conditions, it is further transformed into a nanoscale emulsion. Upon combustion in the cylinder’s combustion chamber, this emulsion eliminates soot formation and nitrogen oxide emissions while maintaining engine power output. These effects have been confirmed through testing conducted by ROUSH.
