Abstract

This numerical analysis study entails creating and assessing a model that is capable of simulating molten metal droplets and the production of metal powder during the Gas Atomization (GA) method. The essential goal of this research aims to gather more information on simulating the process of creating metal powder. The model structure and perspective was built through the application of governing equations and aspects that utilized factors such as gas dynamics, droplet dynamics, energy balance, heat transfer, fluid mechanics and thermodynamics that were proposed from previous studies. The model is very simple and can be broken down into having a set of inputs to produce outputs. The inputs are the processing parameters such as the initial temperature of the metal alloy, the gas pressure and the size of the droplets. Additional inputs include the selection of the metal alloy and the atomization gas and factoring in their properties. The outputs can be designated by the velocity and thermal profiles of the droplet and gas. These profiles illustrate the speed of both as well as the rate of temperature change or cooling rate of the droplets. The main focus is the temperature change and finding the right parameters to ensure thatmore »« less

Gas Atomization of Molten Metal: Part II. Applications

Journal Article Abu-Lebdeh, Taher M. ; Leon, Genaro Perez-de ; Hamoush, Sameer A. ; ... - American Journal of Engineering and Applied Sciences

A numerical model was derived to obtain results for two alloys during the Gas Atomization (GA) method. The model equations and governing equations were implemented through the application of part I data. Aspects such as heat transfer, fluid mechanics, thermodynamics and law of motions were taken into account for the formulation of equations that take gas dynamics, droplet dynamics and energy balance or conservation into consideration. The inputs of the model include: Processing parameters such as the size of the droplets, characteristics of the metal alloy, initial temperature of the molten metal, properties and fractions of the atomization gas andmore »« less

Annual Report: Fuels (30 September 2012)

Technical Report Link, Dirk ; Morreale, Bryan

The thermochemical conversion of fossil fuels through gasification will likely be the cornerstone of future energy and chemical processes due to its flexibility to accommodate numerous feeds (coal, biomass, natural gas, municipal waste, etc.) and to produce a variety of products (heat, specialty chemicals, power, etc.), as well as the inherent nature of the process to facilitate near zero emissions. Currently, the National Energy Technology Laboratory (NETL) Fuels Program has two pathways for syngas utilization: The production of transportation fuels, chemicals, or chemical intermediates. The hydrogen production as an intermediate for power production via advanced combustion turbines or fuel cells.more »« less

Process maps for plasma spray: Part 1: Plasma-particle interactions

Conference GILMORE, DELWYN L ; NEISER, JR, RICHARD A ; WAN, YUEPENG ; ...

This is the first paper of a two part series based on an integrated study carried out at Sandia National Laboratories and the State University of New York at Stony Brook. The aim of the study is to develop a more fundamental understanding of plasma-particle interactions, droplet-substrate interactions, deposit formation dynamics and microstructural development as well as final deposit properties. The purpose is to create models that can be used to link processing to performance. Process maps have been developed for air plasma spray of molybdenum. Experimental work was done to investigate the importance of such spray parameters as gunmore »« less

Novel Cooling Rate Correlations in Molten Metal Gas Atomization

Journal Article Ciftci, N. ; Ellendt, N. ; Coulthard, G. ; ... - Metallurgical and Materials Transactions. B, Process Metallurgy and Materials Processing Science

The cooling rate in molten metal gas atomization is the key determining factor for the microstructure of metal powders. Mathematical expressions for cooling rates often include the melt droplet diameter and a pre-exponential factor describing the materials and gas properties. A new mathematical cooling rate correlation for rapidly solidified melt droplets is proposed based on heat flow considerations during gas atomization. The model approach takes process conditions such as gas-to-melt mass flow ratio and the initial gas temperature into account. The mathematical formulation was experimentally developed using secondary dendrite arm spacing method. For this purpose, a Cu-6wt pct Sn alloy was atomizedmore »« less

NbTa_BCC_SolidSolution_128atoms_VASP6

Dataset Lupo Pasini, Massimiliano ; Samolyuk, German ; Eisenbach, Markus ; ...

We performed density functional theory (DFT) calculations for body-centered-cubic (BCC) structures with 128 lattices sites of solid solution binary alloys niobium-tantalum (Nb-Ta). The electronic structures of alloys have been calculated using Vienna Ab initio Simulation Package (VASP). Within this package the DFT approach is used to reduce many-body Schrodinger equation to set of single particle Kohn-Sham (KS) equations. The generalized electronic exchange-correlation functional is described by generalized gradient approximation with the Perdew-Burke-Ernzerhof parametrization. The electron-ion interactions is described by pseudopotentials developed within the plane-wave basis projector augmented-wave (PAW) approach \cite{PAW}. These pseudopotentials are available at the VASP portal (http://cms.mpi.univie.ac.at/vasp/). Ourmore »« less
