Centrifugal atomization of metal melts is a cost-effective process for powder production and spray deposition. The properties of the as-produced powder and deposit are determined primarily by the characteristics of the atomized droplets, which in turn are largely dependent on the flow development of the melt on the atomizer. This paper develops a model for analysing the flow development of a fu...

AbstractThe atomization mechanism of the gas-liquid multiphase flow through an internally mixing twin-fluid Y-jet atomizer has been studied by examining both internal and external patterns...

Abstract Further innovation in the field of selective laser sintering (SLS) is strongly connected to availability new materials since market dominated by polyamide 12 (>90%). The aim this publication develop a descriptive model for droplet formation process Filament Extension Atomizer predict applicability exploit further polymers SLS process. feasibility was tested, investigated and charact...

A method is described for direct analysis of lead in blood utilizing the carbon rod atomizer. Aliquots of whole blood are analyzed without pre-treatment. Resuits are comparable to those for a similar non-flame technique in which whole blood samples were prediluted with “Triton X-100.” The small sample volumes required and the minimal sample preparation further diminish the possibility of spurio...

In graphite furnace atomic absorption spectrometry (GF-AAS), the atomization process of lead occurring in graphite atomizers with/without a platform plate was investigated when palladium was added to an iron-matrix sample solution containing trace amounts of lead. Absorption profiles of a lead line were measured at various compositions of iron and palladium. Variations in the gas temperature we...

in this study a nonlinear asymmetric instability analysis carried out to study primary atomization of annular liquid sheets emanating from the prefilming airblast atomizer using a perturbation method and potential flow assumption. in this direction, firstly governing equations derived according to potential flow assumption and conservation equations while dynamic and static boundary condition a...

Atmospheric pressure plasmas are emerging as an effective means to produce reactive nitrogen species (RNS) in water with potential applications in irrigation with plasma-treated water for enhanced agriculture. Indeed, roles of RNS, mainly nitric oxide (NO), nitrite (NO2 ) and nitrate (NO3 ) in plant biology have been well studied [1]. The acidity and RNS concentration in treated water have been...
