Abstract:
The paper considers three operational modes of a nozzle-ejector jet system. The study suggests modeling gas-liquid injection as gas permeation through a suspension of liquid droplets in forward flow. In this case, the process will be analogous to gas flow through a fluidized bed. The research determines a pressure drop through the well-known Ergun equation, which is applicable over a wide range of Reynolds numbers. The authors identify the depth of gas-liquid layer formation during phase inversion based on theoretical studies. For the jet apparatus most frequently used in gas-liquid ejector re

The distribution of gas phase bubbles is studied depending on the operating parameters of the apparatus. The value of the local and total gas content, as well as the specific surface of the phase contact, is determined. The gas content and the contact surface of the phases in the downflow pipes of the circulation apparatus with jet injection gas filling are investigated.

Hydraulic calculation of the circulation unit of the appatatus with jet-injection gas filling is considered. Equations of the circulation unit of the apparatus with jet injection gas filling for the gas phase suspension regime along the height of the diplegs are obtained. The equation of the coefficient of hydraulic resistance of the circulation unit is obtained, and a method is developed for selecting a mixing device to overcome the hydraulic resistance in the circulation unit and gas filling of the diplegs

Abstract:
This work aims to investigate Schlieren image correlation velocimetry for flow field quantification of gaseous jet injection in non-manipulable apparatus like flow chambers. Such flow cases often struggle using tracer-based methods: Seeding particles may locally cause technical problems, or the plant design prevents the principal opportunity of tracer adding, both of which lead to a reduced method repertory. This is specifically the case under flow conditions, where contamination of apparatus internals by seeding particles should be avoided completely. Therefore, in this paper, we explore a se

Abstract:
In industries, the task of intensifying the process of dissolving gases in liquid media is relevant, since the time of the technological cycle depends on its course. Absorption processes affect the quality of the finished product and energy costs. In the food industry shell-and-tube jet injectors (SJT) are widespread, in which the mechanical injection of a free-falling jet of liquid surrounding its gas is applied. The aim of this work is to investigate the process of gas entrainment by free jets of water-malt slurry (WSS) in the pipes of the SJT. The set goal was achieved by solving the tasks:

Abstract:
This paper presents the original results of research on an inline jet mixer being an alternative to other, conventional mixing apparatuses used for extraction processes. In particular, researched novel geometry of a jet mixer was subjected to testing of either hydraulic performance or a liquid–liquid extraction process. Inline jet mixers are well suited for mixing gases and liquids and can be used in such processes as extraction, heat exchange, and reaction. In such an apparatus, mixing of liquids takes place by high-velocity injection of one stream into another through a series of small holes

The present paper describes an experimental investigation of the various parameters affecting the operation of industrial pneumatic controllers based on the jet nozzle principle. A test rig was built to monitor supply pressure, air temperature, airflow characteristics, and the static pressure distribution over the flat plate on which the jet impinges. The results demonstrate the existence of a low pressure, separated flow zone, subject to fouling, which subsequently was eliminated by appropriate changes of the injection nozzle geometry.

A two-roll apparatus is used to explore experimentally the detailed fluid mechanics of meniscus roll coating in which inlets are starved and flow rates are small. Both forward and reverse modes of operation (with contra- and co-rotating rolls) are investigated using optical sectioning combined with dye injection and particle imaging techniques. That part of parameter space where meniscus coating occurs is identified by varying the roll separation and roll speeds and hence flow rate and capillary number.Key features of the flow structures identified in the forward mode include two large eddies
