A continuous stream of an inert gas is passed through the furnace, protecting the graphite tube from oxidation and removing the gaseous products produced during atomization. A power supply is used to pass a current through the graphite tube, resulting in resistive heating. Figure 10.45:Diagram showing a cross-section of an electrothermal analyzer.

Atomization Concept and Theory - Graco

Answers to Progress Check 1. B. A spray is a collection of a variety of sizes of fluid droplets moving in a controlled fashion. 2. D. Surface tension causes an atomized liquid to break up into spherical droplets. 3. A. Droplets are small particles of liquid. 4. C. Atomization is the process of breaking up liquids into droplets. 5. D. Surface tension is the force that causes fluids to pull Breakup of thin liquid sheets through holehole and hole As recently shown in a quasi-planar liquidgas atomization (Ling et al. Reference Ling, Fuster, Zaleski and Tryggvason 2017), the minimum thickness of the formed liquid sheet, after being stretched by the surrounding fast gas stream, is between $25$ and $50\ \mathrm {\mu }\textrm {m}$ corresponding to an Ohnesorge number (the ratio of viscous

Comparison of spray quality for two different flow

Comparison of spray quality for two different flow configurations: nozzle types are applied in high pressure entrained flow gasifiers (EFG), where atomization is characterized by low Gas-to-liquid ratio (GLR) and high fuel viscosity. Chigier [12] and Zhao et al [10], the nozzle has parallel flow channels. Figure 1. Experiment on the Breakup of Liquid Jets in Different Jul 01, 2019 · Abstract. The experiment is conducted with a high-speed camera to investigate the breakup processes of liquid jets in uniform, shear-laden, and swirling cross-airflows. The liquid used in the test is water, the nozzle diameter is 2 mm, and the liquid-to-air momentum flux ratio ranges from 5 to 3408.5. The results indicate that liquid jets break

Gas Atomisation - an overview ScienceDirect Topics

A. Lawley, in Encyclopedia of Materials:Science and Technology, 2001 1.2 Gas Atomization. In gas atomization, the stream of liquid metal is disrupted by a high velocity gas (air, nitrogen, argon, or helium). Worldwide annual tonnage of gas atomized powders is much less than that of water atomized powders:about 300,000 tyr 1 for air atomization and 50,000 tyr 1 for inert gas atomization Influence of Atomization Gas on the Particle Formation To analyze the atomization gas pressure influence on the particle formation and atomization the spraying parameters, such as voltage and current were kept constant, Table 1.

(Miyamoto et al., 2002), transport (Tan et al., 2007), mixing (Shilton et al., 2008, 2014), and jetting (Guo et al., 2014; Tan et al., 2009)can be induced within the liquid body depending on the magnitude of the surface acceleration on the substrate, itself controlled by Liquid Jet Instability and Atomization in a Coaxial Gas Abstract An overview of the near and far-field breakup and atomization of a liquid jet by a high speed annular gas jet is presented. The various regimes of liquid jet breakup are discussed in the parameter space of the liquid Reynolds number, the aerodynamic Weber number, and the ratio of the momentum fluxes between the gas and the liquid streams. Recent measurements of the gas-liquid

Melt Atomization - an overview ScienceDirect Topics

The hardware-technological circuit (Figure 12.3) most widely used in Russia includes the high compressed gas (air or inert gas) atomization systems and powder separation. Devices with dry separation of atomization products (in cyclones, multi-cyclones, bag filters) and with melt atomization into liquid medium (hydrocarbons or aqueous solutions Microstructure and properties of CoCrNi medium-entropy Therefore, gas-atomized powders also have potential for additive manufacturing of MEA, such as CoCrNi. In addition, the combination of gas atomization and spark plasma sintering (SPS) could be used to overcome the above fabrication drawbacks owing to the smaller risk of contamination, grain refinement, reduced segregation, etc.
