Production of metal powders by gas atomization using swirl and non-swirl nozzles
Nihon Kikai Gakkai ronbunshu, 2022 Gas atomization, in which high-pressure gas jet impinges on molten metal stream from the melt tube to atomize it, is a popular method of producing fine metal powders. In this study, we focused on a swirling flow of the injection gas as a factor affecting

Numerical modeling of flows with flow swirling [PDF]
Computer Research and Modeling, 2013 This paper is devoted to investigation of the swirl flows. Such flows are widely used in various industrial processes. Swirl flows can be accompanied by time-dependent effects, for example, precession of the vortex core. In turn, the large-scale fluctuations due to the precession of the vortex can cause damage of structures and reduce of equipment ...
