Simulation Study of the Swirl Spray Atomization of a Bipropellant Thruster under Low Temperature Conditions

open access: yesEnergies, 2022
The spray atomization of an injector significantly influences the performance and working life span of a bipropellant thruster of a spacecraft. Deep space exploration requires the thruster to be able to operate reliably at a low temperature range from ...

Secondary Rontgen Rays and Atomic Weight [PDF]

open access: yesNature, 1906
IN papers on secondary Rontgen radiation and polarised Rontgen radiation I have shown that all the phenomena of secondary radiation (as indicated by an electroscope placed several centimetres from the radiator) may, from substances of low atomic weight, be accounted for by considering the corpuscles or electrons constituting the atoms, to be ...

Primary break-up and atomization characteristics of a nasal spray.

open access: yesPLoS ONE, 2020
The primary objective of this research was to extract the essential information needed for setting atomization break up models, specifically, the Linear Instability Sheet Atomization (LISA) breakup model, and alternative hollow cone models.

Investigation on close-coupled gas atomization for Fe-based amorphous powder production via simulation and industrial trials: Part II. Particle flight and cooling during secondary atomization

open access: yesJournal of Materials Research and Technology, 2023
A two-way coupling Discrete Phase Model (DPM) is applied to calculate the secondary atomization process. The particle flight and cooling processes are studied under different process parameters.

Effect of Liquid Properties on the Characteristics of Collisions between Droplets and Solid Particles

open access: yesApplied Sciences, 2022
The characteristics of the collisions of droplets with solid particles (52,100 steel) were experimentally studied when varying the key liquid properties: viscosity (1–6.3 mPa·s), surface tension (72.69–36.1 mN/m) and interfacial (liquid-liquid) tension ...

On the Influence of Nozzle-generated Coherent Structures on the Primary Atomization of Fuel Jets: Paper 144

open access: yes, 2021
The application of a 3-phase VOF-LES solver [1] to the simulation of two transparent nozzle replicas is presented. The solver, implemented in the OpenFOAM Technology, is able to capture in-nozzle cavitation and fuel atomization near the nozzle exit ...

Effects of gas viscosity and liquid-to-gas density ratio on liquid jet atomization in crossflow

open access: yesAIP Advances, 2023
Atomization of liquid jets in gaseous crossflows has many natural and industrial applications, for example, in fuel atomization in gas turbine engines, rocket engines, film cooling, and, recently, suspension and solution precursor plasma spraying ...

Interaction between high-velocity gas and liquid in gas atomization revealed by a new coupled simulation model

open access: yesMaterials & Design, 2021
Due to the high efficiency and low cost, gas atomization (GA) has been widely applied to produce metal powders. In this paper, the GA process is first modeled by combining the volume of fluid (VOF) model with dynamic adaptive mesh and the discrete phase ...

Numerical simulation of primary and secondary atomization

open access: yesComptes Rendus. Mécanique, 2013
The physics of the atomization process involves many complex phenomena, which occur at different scales of space and time. The numerical study of such a problem is a great challenge for different reasons. Large density ratios, presence of a singular surface tension force, interface localization and transport, mass conservation, all of these make ...
