本實驗利用四種不同性質的溶液n-Hexadecane( )、n-Heptane( )、methanol( )和 ,分別以可溶和不可溶兩種溶液,以Ink-Jet printing method 產生雙向自由液滴(Free droplet stream)於空氣中撞擊後,進入高溫環境燃燒。主要研究其點火延遲、燃燒速率、微爆現象及火焰縮口(flame shrinkage)。在互溶油料方面,並將撞擊之結果和同比例、同大小但無撞擊的預混液滴燃燒現象作一比較。
實驗結果發現可互溶之 和 互相撞擊後燃燒,其燃燒特質和預混時一樣。而 和 撞擊後燃燒會有微爆、熄滅和水滴微爆、不能點燃四種情況,且點火延遲隨水滴尺寸增加而增加。 和 撞擊後燃燒則會引發劇烈微爆和極不穩定的點火延遲。
