Reference number : GC-2017-Q4-00487, amendment number : , agreement type : G, recipient legal name : Dolatabadi, Ali (Concordia University)|Dolatabadi, Ali (Université Concordia), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Gas atomization process is commonly used to produce metallic powders by rapid fragmentation of the flow of_x000D_
melt stream falling due to gravitational force. Fragmentation of melt stream starts with the formation of_x000D_
ligaments (primary atomization) followed by further breakup and the formation of spherical droplets (i.e._x000D_
secondary breakup). The effectiveness of gas atomization process directly influences the powder size_x000D_
distribution produced in a powder manufacturing plant. Powders produced with this process are being used for_x000D_
critical metallization applications and they must meet certain specifications. The ability to simulate the gas_x000D_
atomization particularly the zone of interaction between gas and melt stream is a valuable advancement for the_x000D_
optimization of process parameters in order to meet the required specifications. In collaboration with Eutectic_x000D_
Canada Inc., a leading powder manufacturer, we are aiming to calculate the optimized atomizing gas flow and_x000D_
molten metal temperature in order to prevent the molten metal solidification during the atomization process_x000D_
and importantly predict the final particle size distribution. In this project, a Computational Fluid Dynamics_x000D_
(CFD) simulation of multiphase flow and heat transfer will be performed. We are expecting that the results of_x000D_
this study will allow Eutectic Canada Inc. to enhance its role in the fabrication of controllable and repeatable_x000D_
metallic powders used in advanced additive manufacturing process as well as various coating processes such as_x000D_
HVOF and HVAF. Moreover, end users from aerospace, automotive, and energy sectors will benefit from the_x000D_
project by enhancing their competitiveness and by contributing to the economy of Quebec and Canada., program purpose french : Gas atomization process is commonly used to produce metallic powders by rapid fragmentation of the flow of_x000D_
