. The key concept of hybrid atomization is to control the liquid film formation on disk for fine powder production. Low-pressure gas atomization was utilized to promote the formation of a very thin.... In some conventional atomization methods such as centrifugal atomization and confined gas atomization, a liquid film was found to form before the final breakup[1]. It seems that the liquid film......
