lithum can be de termined both by atomic absorption spectroscopy andflame emission spectroscopy. we have used the later method with a zeiss model pmqli spectro photometer fitt ed with ante-chamber atomizer and a potensiome rric line recorder. accurate ana lysis for the clement was acco mplished due to a sophisracared measuring instrument.

Spray Diagnostics Measurements of an air blast atomizer at ambient pressure conditions are presented. The atomizer was developed by United Technologies Aerospace Systems as part of a combustor design for NASA's Environmentally Responsible Aviation (ERA) N+2 advanced, low NOx combustor technologies program. The goals of this combustor design is to meet or exceed the N+2 LTO NOx goal of 75% reduc...

Due to the significant reduction in water droplet size caused by strong air-water interaction spray nozzle, air-mist is one of promising technologies for achieving high-rate heat transfer. This study numerically analyzed produced a flat-fan atomizer using three-dimensional computational fluid dynamics simulations, and multivariable linear regression was used develop correlation predict transfer...

A temporal stability analysis was carried out to model the atomization of a swirling viscous non-Newtonian annular liquid sheet emanating from an air-blast atomizer subject to inner and outer inviscid swirling air streams. The dimensionless dispersion equation that governs the instability of a viscous non-Newtonian annular liquid sheet under swirling air streams was obtained. Numerical solution...

We compared a stabilized-temperature L'vov platform furnace containing an end-heated graphite atomizer (HGA) and transverse Zeeman background-correction system with a side-heated furnace system (transversely heated graphite atomizer; THGA) containing a longitudinal Zeeman background-correction system for the determination of aluminum in plasma and urine. The regression statistics for the correl...

PURPOSE The purpose of this investigation was to compare the pharmacokinetics of midazolam following intravenous, intranasal drop, and nasal-atomizer administration in beagle dogs. METHODS Six animals weighing 9-13 kg were used in a repeated-measure design, group assignment based on route of drug administration. Midazolam (1.5 mg/kg) was administered with the delivery route based on group ass...

A widely distributed spray is an important feature for atomizer which required in various applications such as gas cooling, turbine combustion, and fluidized bed granulator. Pressure-swirl example of provides a wide angle through the swirling effect inside atomizer. One parameters affecting geometrical constant, K. Another parameter pressure-swirl discharge coefficient, Cd. Discharge coefficien...

Abstract Metallic powders for additive manufacturing (AM) processes are primarily produced by gas atomization, which consists of three steps: melting, atomization and cooling. In the present work, we report on refurbishing a laboratory-scale atomizer. The equipment facilitates small-scale useful developing tailored specifically to metal AM (e.g. binder jetting, laser powder-bed fusion direct en...
