A Lagrangian-Eulerian methodology is developed for the numerical simulation of a gas-solid reactive flow. The SO2-NOx Adsorption Process (SNAP) is taken as a test case. A three-dimensional time dependent simulation is performed. A notional particle based Monte-Carlo algorithm is used to solve the transported composition Probability Density Function (PDF) equations to determine the gas phase com...

Until quite recently, theories on thermophoresis of particles predicted very low thermophoretic velocities of metal particles in liquids. This prediction was based on the understanding that the very high thermal conductivities of metals relative to most liquid media resulted in quite low temperature gradients across the metal particle thereby leading to low net force on the particle. In this pa...

The purpose of the work is determining efficiency injection equipment with ferroalloys different fractional composition, density and flow deep into iron-carbon melt, taking account parameters (length diameter pipeline pressure in powder-feeder). analytical review literature performed, which confirmed advantage powder a teeming ladle compared to traditional technologies deoxidation alloying. Bas...

The current work investigates the performance of a single-stage, bench-scale system using a spray dryer to treat produced water. The produced water is generated in three large reservoirs of Ahvaz, Maroon, and Mansouri fields, which have different compositions but the same high total dissolved solids (TDS) and total organic carbon (TOC). The results of this study indicate that the newly develope...

Spatially resolved analysis of the composition of the gas-phase during chemical vapor deposition depends on an effective sampling apparatus. In the present work, a novel in-situ sampling and cooling apparatus was presented, which is connected directly to an online GC/MS. Simulations of the temperature distribution in the cooling apparatus show that sample gas can be cooled down to 600 K in shor...

Noble gas analysis can be performed on two types of ice core samples. First, atmospheric air, trapped in bubbles in polar ice, can be extracted and analyzed for its noble gas composition. Variations in the isotopic and elemental composition of noble gases reveal changes in the composition of the paleoatmosphere or the impact of climate-related physical processes acting when the air was enclosed...

In this study, ZnO/ZnAl 2 O 4 /Zn TiO composite nanostructured thin films are deposited assisted with hollow-cathode glow discharge (HCD). The using various argon-oxygen gases mixture (0–50% ), and its effect on film quality, optical electrical properties is examined. Remarkably, instead of metallic targets, ZnO, 2, Al 3 powders filled in used for deposition, thus no specific targets required t...
