Swirling efects in atmospheric plasma spraying process: experiments and simulation
Experimental evidence of swirling effects in 3D trajectories of in-flight particles is presented based on static and dynamic footprints analysis as a function of stand-o_ distance of Al2O3 deposited employing a Metco-9MB torch. Swirling effects were validated with a proprietary computational fluid dynamics (CFD) code that considers an argon-hydrogen plasma stream, in-flight particles trajectories, both creating the spray cone, and particle impact to form a footprint on a fixed substrate located at different distances up to 120 mm. Static and dynamic footprints showed that swirl produces a slight deviation of individual particle trajectories and thus footprint rotation, which may affect coating characteristics. ; John McKelliget (U. of Massachusetts), coautor. ; Author contributions: conceptualization, J.M.-S. and G.T.-M.; methodology, I.M.-V.; software, I.M.-V., J.M. and G.T.-M.; formal analysis, A.G.M.-G, H.R.-L., J.M.-S.; investigation, I.M.-V.; resources, C.A.P.-S., J.M. and G.T.-M.; data curation, I.M.-V.; writing—original draft preparation, I.M.-V., A.G.M.-G, H.R.-L., J.M.-S. and C.A.P.-S.; writing—review and editing, J.M.-S., C.A.P.-S., J.M. and G.T.-M.; visualization, A.G.M.-G. and H.R.-L.; supervision, J.M.-S., C.A.P.-S., J.M. and G.T.-M.; project administration, I.M.-V., J.M. and G.T.-M.; funding acquisition, J.M. and G.T.-M.
