The strong scattering of visible light by spray droplets has severely impeded the ability of optical diagnostics to probe dense sprays. X-rays interact more weakly with spray droplets than visible light; as such, multiple scattering effects are rarely important in the x-ray regime. As such, x-ray radiography (which relies on absorption) and x-ray phase-contrast imaging (which relies on subtle r...

Investigation of the JJPW-G100 air-assisted spraying dust suppression device was performed to obtain reasonable installation angle nozzle in device. First, an equal-scale physical model established, and then effect on atomizing performance investigated in-depth via numerical simulation. Results showed that imposed no significant range device, while initial falling spray field increased with inc...

Spray-drying is a widely used industrial technique and has shown an immense potential in the fields of nanoscience technology. This due to its ability synthesize microgranules consisting correlated nanostructures using evaporation induced assembly through bottom-up approach. Although nature correlation among constituent nanoparticles their size distribution could earlier be obtained by conventi...

Liquid atomization is applied in nanostructure dense coating technology to inject suspended nano-size powder materials into a suspension plasma spray (SPS) torch. This paper presents the effects of the atomization parameters on the nanoparticle processing. A numerical model was developed to simulate the dynamic behaviors of the suspension droplets, the solid nanoparticles or agglomerates, as we...

Pressure swirl atomizers are widely used in gas turbine combustor; this paper is aimed at researching the effect of low ambient pressure (0.1 MPa to 0.01 MPa, lower than an atmosphere) on spray cone angle atomizer. The captured by high-speed photography; then, image post program process magnitude. A mathematical model a single droplet’s movement and trajectory based force analysis proposed vali...

Abstract This paper summarises a series of large-scale fire suppression tests conducted to simulate in the big surface and/or sprinkling. The subject this is research on water spraying with use Turbo Jet 2011 water-foam nozzle manufactured by Supon Białystok. results discuss pressure losses caused flow through discharge hose, spray angle, and intensity greatest stream ranges highest maximum val...

Ballistic simulation of the spray sprinkler for self-propelled irrigation machines requires the incorporation of the effect of the jet impact with the deflecting plate. The kinetic energy losses produced by the jet impact with the spray plate were experimentally characterized for different nozzle sizes and two working pressures for fixed spray plate sprinklers (FSPS). A technique of low speed p...
