The high efficiency of hole cleaning is essential and critical for drilling horizontal wells. In
this study, the effects of four-lobed drill pipe on drill cuttings transport behaviors are …

Impinging-jet injectors, liquid–liquid coaxial swirl injectors, and liquid–liquid pintle injectors
are representative liquid–liquid injectors in liquid rocket engines (LRE). For these liquid …

The backflow of high-temperature products in an engine's combustion chamber is a key
issue which can significantly reduce combustion efficiency. This is particularly problematic …

The following article proposes the design of a bi-centrifugal atomizer that allows the
interaction of sprays from two fluids (water and liquid nitrogen). The liquid nitrogen (LN2) is …

Push chain moist-mix concrete spraying machine is widely used in shotcrete construction
processes, but shotcrete surplus has always been the main problem affecting work …

This study discusses the development of a mathematical model that is capable of predicting
the drop size mean diameter of the spray generated by a pressure swirl atomizer …

This article addresses the study of internal flow dynamics within a cryogenic chamber
designed for freezing food using liquid nitrogen injection. The chamber features a circular …

This study delves into the examination of internal flow characteristics within closed (with
nozzles) and open-end pressure-swirl atomizers (lacking nozzles). The number of inlet …

The conditions for merging two liquid sheets in a coaxial pressure-swirl external mixing
injector were assessed experimentally and numerically. Fast imaging was employed based …

Using the volume of fluid (VOF) method in the approximation of 2D axisymmetric swirling
flow, the primary atomization of a kerosene film in an air-assist centrifugal atomizer of an …
