In　order　to　improve　the　atomization　effect　of　the　snowmaker,　the　numerical　simulation　method　was　used　to　study　the　influence　of　the　structure　parameters　of　the　snowmaker,　including　the　mixing　chamber　length　and　inlet　diameter　ratio,　on　the　atomization　effect　of　the　snowmaker,　and　the　influence　of　the　gas-liquid　relative　velocity　on　the　atomization　particle　size　distribution　was　briefly　analysed.　The　results　show　that　different　structural　parameters　directly　affect　the　average　diameter　of　the　droplet.　In　order　to　ensure　the　atomization　effect,　the　suitable　length　of　the　mixing　chamber　is　18　∼　24　mm,　and　the　angle　between　the　inlet　and　the　average　diameter　of　the　droplet　is　positively　correlated,　which　provides　a　reference　for　optimizing　the　structural　parameters　of　the　snow　crystal　sprayer.　©　COPYRIGHT　SPIE.　Downloading　of　the　abstract　is　permitted　for　personal　use　only.
